GENERAL DESCRIPTION The TZA3044 is a high gain limiting amplifier that is designed to process signals from fibre optic preamplifiers like the TZA3043 and TZA3023. It is pin compatible with the NE/SA5224 and NE/SA5225 but with extended power supply range, and needs less external components. Capable of operating up to 1.25 Gbits/s, the chip has input signal level detection with a user-programmable threshold. The data and level detection status outputs are differential outputs for optimum noise margin and ease of use. The TZA3044B has the same functionality as the TZA3044, but with TTL compatible status outputs (pins ST and STQ), and TTL compatible JAM input.

The input signal will be amplified and limited to differential PECL output levels (see Fig.1). The input buffer A1 presents an impedance of approximately 4.5 k to the data stream on the inputs DIN and DINQ. The input can be used both single-ended and differential, but differential operation is preferred for better performance. Because of the high gain of the postamplifier, a very small offset voltage would shift the decision level in such a way that the input sensitivity decreases drastically. Therefore a DC offset compensation circuit is implemented in the TZA3044, which keeps the input of buffer A3 at its toggle point in the absence of any input signal. An input signal level detection is implemented to check if the input signal is above the user-programmed level. The outcome of this test is available at the PECL outputs ST and STQ (TTL for the TZA3044B). This flag can also be used to prevent the PECL outputs DOUT and DOUTQ from reacting to noise in the absence of a valid input signal, by connecting pin STQ to pin JAM. This guarantees that data will only be transmitted when the input signal-to-noise ratio is sufficient for low bit error rate system operation. PECL logic The logic level symbol definitions for PECL are shown in Fig.4. Input biasing The inputs, pins DIN and DINQ, are DC biased at approximately 2.1 V by an internal reference generator (see Fig.5). The TZA3044 can be DC coupled, but AC coupling is preferred. In case of DC coupling, the driving source must operate within the allowable input signal range (1.3 V to VCCA). Also a DC offset voltage of more than a few millivolts should be avoided, since the internal DC offset compensation circuit has a limited correction range. TZA3044; TZA3044B If AC coupling is used to remove any DC compatibility requirement, the coupling capacitors must be large enough to pass the lowest input frequency of interest. For example, 1 nF coupling capacitors react with the internal 4.5 k input bias resistors to yield a lower -3 dB frequency of 35 kHz. This then sets a limit on the maximum number of consecutive pulses that can be sensed accurately at the system data rate. Capacitor tolerance and resistor variation must be included for an accurate calculation. DC-offset compensation A control loop connected between the inputs of buffer A3 and amplifier A1 (see Fig.1) will keep the input of buffer A3 at its toggle point in the absence of any input signal. Because of the active offset compensation which is integrated in the TZA3044, no external capacitor is required. The loop time constant determines the lower cut-off frequency of the amplifier chain, which is set at approximately 850 Hz. Input signal level detection The TZA3044 allows for user-programmable input signal level detection and can automatically disable the switching of the PECL outputs if the input signal is below a set threshold. This prevents the outputs from reacting to noise in the absence of a valid input signal, and insures that data will only be transmitted when the signal-to-noise ratio of the input signal is sufficient for low bit-error-rate system operation. Complementary PECL (TTL for the TZA3044B) flags (pins ST and STQ) indicate whether the input signal is above or below the programmed threshold level. The input signal is amplified and rectified before being compared to a programmable threshold reference. A filter is included to prevent noise spikes from triggering the level detector. This filter has a nominal 1 s time constant and additional filtering can be achieved by using an external capacitor between VCCA and pin CF (the internal driving impedance nominally is 25 k). The resultant signal is then compared to a threshold current through pin RSET. This current can be set by connecting an external resistor between VCCA and pin RSET, or by forcing a current into pin RSET (see Fig.6). 2002 Jul 19 5 Philips Semiconductors Product specification SDH/SONET STM4/OC12 and 1.25 Gbits/s Gigabit Ethernet postamplifiers The relationship between the threshold current and the detected input voltage is approximately: I RSET = 0.0018 x ( V DIN - V DINQ ) [ A ] (1) Dissipation TZA3044; TZA3044B In the formulas (1) and (3), the voltage on pins DIN and DINQ is measured as peak-to-peak value. Since the voltage on pin RSET is held constant at 1.5 V below VCCA, the current flowing into this pin will be: 1.5 I RSET = ------------ [ A ] R ADJ (2) Since the thermal resistance from junction to ambient Rth(j-a) of the TSSOP package is higher than the thermal resistance of the SO package (see Chapter "Thermal characteristics"), the dissipation should be considered when using the TZA3044TT version. The formula to calculate the worst case die temperature is: T j = T amb + R th ( j - a ) x P max where Tj = junction temperature Tamb = ambient temperature Rth(j-a) = thermal resistance from junction to ambient Pmax = maximum power dissipation. For the TZA3044T (SO package), the worst case die temperature Tj = 85 + 115 x 0.3 = 119.5 C which is below the maximum operating temperature. For the TZA3044TT (TSSOP package), the worst case die temperature Tj = 85 + 150 x 0.3 = 130 C which is higher than the maximum operating temperature, and therefore strongly discouraged. It is recommended to lower the thermal resistance from junction to ambient, e.g. by means of a dedicated board layout. However, if the ambient temperature is limited to 75 C or the power supply is limited to 3.3 0.3 V, the junction temperature will stay below the maximum value without further precautions. Output circuits The output circuit of ST and STQ is given in Fig.7. The output circuit of DOUT and DOUTQ is given in Fig.8. Some PECL termination schemes are given in Fig.9. (4) Combining these two formulas results in a general formula to calculate RADJ for a given input signal level detection: 830 R ADJ = ------------------------------------- [ ] ( V DIN - V DINQ ) (3) Example: Detection should occur if the differential voltage of the input signals drops below 4 mV (p-p). In this case, a reference current of 0.0018 x 0.004 = 7.2 A should flow into pin RSET. This can be set using a current source or simply by connecting a resistor of the appropriate value. The resistor must be connected between VCCA and pin RSET. In this example the value would be: 830 R ADJ = -------------- = 207.5 k 0.004 The hysteresis is fixed internally at 3 dB electrical. In the example of above, a differential level below 4 mV (p-p) of the input signal will drive pin ST to LOW, and an input signal level above 5.7 mV (p-p) will drive pin ST to HIGH. A function is provided to automatically disable the signal transmission when the chip senses that the input signal is below the programmed threshold level. This function can be put into operation by connecting pin JAM with pin STQ. When the input signal is below the programmed threshold level, the data outputs are then forced to a predetermined state (pin DOUT = LOW and pin DOUTQ = HIGH). Response time of the input signal level detection circuit is determined by the time constant of the input capacitors, together with the filter time constant (1 s internal plus the additional capacitor at pin CF). For SDH/SONET applications couple capacitors of 1.5 nF are recommended, leading to a high-pass frequency of approximately 30 kHz and a maximum assert time of 30 s. 2002 Jul 19 6 Philips Semiconductors Product specification SDH/SONET STM4/OC12 and 1.25 Gbits/s Gigabit Ethernet postamplifiers TZA3044; TZA3044B handbook, halfpage VCC VOH(max) VOH(min) (1) (2) VOL(max) VOL(min) MGS812 GND (1) Output signal on pin DOUT or pin ST; complementary to output signal (2).

A more in-depth account of soldering ICs can be found in our "Data Handbook IC26; Integrated Circuit Packages" (document order number 9398 652 90011). There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended. Reflow soldering Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method. Typical reflow peak temperatures range from 215 to 250 C. The top-surface temperature of the packages should preferable be kept below 220 C for thick/large packages, and below 235 C for small/thin packages. Wave soldering Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems. To overcome these problems the double-wave soldering method was specifically developed. TZA3044; TZA3044B If wave soldering is used the following conditions must be observed for optimal results: * Use a double-wave soldering method comprising a turbulent wave with high upward pressure followed by a smooth laminar wave. * For packages with leads on two sides and a pitch (e): - larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be parallel to the transport direction of the printed-circuit board; - smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves at the downstream end. * For packages with leads on four sides, the footprint must be placed at a 45 angle to the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Manual soldering Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C. 2002 Jul 19 24 Philips Semiconductors Product specification SDH/SONET STM4/OC12 and 1.25 Gbits/s Gigabit Ethernet postamplifiers TZA3044; TZA3044B Suitability of surface mount IC packages for wave and reflow soldering methods PACKAGE(1) BGA, LBGA, LFBGA, SQFP, TFBGA, VFBGA HBCC, HBGA, HLQFP, HSQFP, HSOP, HTQFP, HTSSOP, HVQFN, HVSON, SMS PLCC(4), SO, SOJ LQFP, QFP, TQFP SSOP, TSSOP, VSO Notes 1. For more detailed information on the BGA packages refer to the "(LF)BGA Application Note" (AN01026); order a copy from your Philips Semiconductors sales office. 2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum temperature (with respect to time) and body size of the package, there is a risk that internal or external package cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the Drypack information in the "Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods". 3. These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 4. If wave soldering is considered, then the package must be placed at a 45 angle to the solder wave direction. The package footprint must incorporate solder thieves downstream and at the side corners. 5. Wave soldering is suitable for LQFP, TQFP and QFP packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 6. Wave soldering is suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm. not suitable not suitable(3) SOLDERING METHOD WAVE REFLOW(2) suitable suitable suitable suitable suitable suitable not not recommended(4)(5) recommended(6) 2002 Jul 19 25 Philips Semiconductors Product specification SDH/SONET STM4/OC12 and 1.25 Gbits/s Gigabit Ethernet postamplifiers DATA SHEET STATUS DATA SHEET STATUS(1) Objective data PRODUCT STATUS(2) Development TZA3044; TZA3044B DEFINITIONS This data sheet contains data from the objective specification for product development.
