| Micrel, Inc. ULTRA-PRECISION DIFFERENTIAL 400mV LVPECL LINE DRIVER/RECEIVER WITH INTERNAL TERMINATION Precision Edge(R) SY58602U Precision Edge(R) SY58602U FEATURES Guaranteed AC performance over temperature and voltage: * DC-to >10.7Gbps data rate throughput * DC-to >7GHz clock fMAX * <250ps In-to-Out tpd * tr / tf <70ps Ultra low-jitter design: * <1psRMS random jitter * <10psPP deterministic jitter * <10psPP total jitter (clock) Minimum input swing 200mV (|IN-/IN|) Unique, patent-pending input termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS) Typical 400mV LVPECL output swing Power supply 2.5V 5% or 3.3V 10% -40C to 85C industrial temperature range Available in an ultra-small (2mm x 2mm) 8-pin MLF(R) package Precision Edge(R) DESCRIPTION The SY58602U is a 2.5V/3.3V precision, high-speed, differential receiver capable of handling clocks up to 7GHz and data streams up to 10.7Gbps. The differential input includes Micrel's unique, 3-pin input termination architecture that allows users to interface to any differential signal (AC- or DC-coupled) as small as 200mVpp without any level shifting or termination resistor networks in the signal path. The outputs are 400mV LVPECL, with extremely fast rise/fall times guaranteed to be less than 70ps. The SY58602U operates from a +2.5V 5% supply or a +3.3V 10% supply and is guaranteed over the full industrial temperature range of -40C to +85C. For applications that require CML outputs, consider the SY58600U or for 800mV LVPECL outputs the SY58601U. The SY58602U is part of Micrel's high-speed, Precision Edge(R) product line. All support documentation can be found on Micrel's web site at: www.micrel.com.

PIN DESCRIPTION Pin Number 1, 4 Pin Name IN, /IN Pin Function Differential Input: This input pair is the signal to be buffered. These inputs accept AC or DCcoupled signals as small as 100mV. Each pin of this pair internally terminates to a VT pin through 50. Note that this input will default to an indeterminate state if left open. Please refer to the "Input Interface Applications" section for more details. Input Termination Center-Tap: Each side of the differential input pair terminates to this pin. The VT pin provides a center-tap to a termination network for maximum interface flexibility. See "Input Interface Applications" section for more details. Reference Output Voltage: This output biases to VCC -1.2V. Connect to VT pin when ACcoupling the input. Bypass with 0.01F low ESR capacitor to VCC. Maximum current source or sink is 0.5mA. See "Input Interface Applications" section. Positive Power Supply. Bypass with 0.1F||0.01F low ESR capacitors as close to the VCC pin as possible. Differential 100K LVPECL Output: This LVPECL output is the output of the device Terminate through 50 to VCC -2.0V. See "Output Interface Applications" section. Ground. Ground pin and exposed pad must be connected to the same ground plane. 2 VT 3 VREF-AC 8 7, 6 5 VCC Q, /Q GND, Exposed M9999-022007 hbwhelp@micrel.com or (408) 955-1690 2 Micrel, Inc.

This is a stress rating only and functional operation is not implied for conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. 2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings. 3. Due to the limited drive capability use for input of the same package only. 4. Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential on the PCB. JB uses 4-layer JA in still-air, unless otherwise stated. 5. The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. 6. Includes current through internal 50 pull-ups.

The circuit is designed to meet the DC specifications shown in the above table after thermal equilibrium has been established. 9. High-frequency AC electricals are guaranteed by design and characterization. 10. Random jitter is measured with a K28.7 comma detect character pattern, measured at 2.5Gbps/3.2Gbps. 11. Deterministic jitter is measured at 2.5Gbps/3.2Gbps with both K28.5 and 223-1 PRBS pattern. 12. Cycle-to-cycle jitter definition: the variation of periods between adjacent cycles, Tn-Tn-1 where T is the time between rising edges of the output signal. 13. Total jitter definition: with an ideal clock input of frequency fMAX, no more than one output edge in 1012 output edges will deviate by more than the specified peak-to-peak jitter value.
