1 description lt c2311/lt c2310 single 16-bit/14-bit/12-bit, 5msps/2msps, serial, high speed sar adcs demonstration circuit 2425a features the lt c ? 2311 family. with up to 5msps, these differential, single channel, 16-bit, serial, high speed successive approximation register (sar) adcs are available in a 16- lead msop package. the LTC2311 family has an internal 20ppm/c maximum drift reference and an spi-compatible serial interface that supports cmos and lvds logic. note the demo board is configured for cmos operation by default; see the note under jp3 for lvds operation. the following text refers to the LTC2311 , but applies to all members of the fam - ily, the only difference being the sample rate and/or the l , lt, ltc, ltm, linear technology and the linear logo are registered trademarks and pscope is a trademark of linear technology corporation. all other trademarks are the property of their respective owners. boar d p hoto number of bits. the dc2425a demonstrates the dc and ac performance of the LTC2311 in conjunction with the dc890 pscope? data collection board. alternatively, by connecting the dc2425a into a customer application, the performance of the LTC2311 can be evaluated directly in that circuit. design files for this circuit board are available at http://www.linear.com/demo/dc2425a figure 1. dc2425a connection diagram hp8642b bpf ?9.5v dc gnd +9.5v dc dc power supply hp8642b bpf to dc890b dc2425a f01 dc2425af demo manual dc2425a
2 quick s tart p roce d ure demonstration circuit 2425a is easy to set up and evaluate for performance. refer to figure 1 and follow the proce - dure below. n connect the dc2425a to a dc890 usb high speed data collection board using edge connector p1. n connect the dc890 to a host pc with a standard usb a/b cable. n apply a low jitter signal source to j3 to test channel?1. note that the dc2425 a is capable of accepting a differential input signal as well as a single-ended signal. see the hardware setup section for the jumper positions that correspond to these configurations. n as a clock source, apply a low jitter 10dbm sine wave or square wave to connector j5. see table 1 for maximum clock frequencies. note that j5 has a 50 termination resistor to ground. n run the pscope software (pscope.exe version k73, or later) supplied with the dc890 or download it from www.linear.com/software. complete software doc- umentation is available from the help menu. updates can be downloaded from the tools menu. check for updates periodically, as new features may be added. the pscope software should recognize the dc2425a and configure itself automatically. n click the collect button (figure 2) to begin acquiring data. the collect button then changes to pause, which can be used to stop data acquisition. a ssem b ly o ptions table 1. dc2425a assembly options version u1 part number max conversion rate # of bits max clock frequency dc2425a-a LTC2311cmse-16#pbf 5msps 16 105mhz dc2425a-b ltc2310cmse-16#pbf 2msps 16 42mhz dc2425a-c LTC2311cmse-14#pbf 5msps 14 105mhz dc2425a-d ltc2310cmse-14#pbf 2msps 14 42mhz dc2425a-e LTC2311cmse-12 #pbf 5msps 12 105mhz dc2425a-f ltc2310cmse-12#pbf 2msps 12 42mhz figure 2. dc2425a pscope screenshot dc2425af demo manual dc2425a
3 d rive o ptions there are several ways to drive the LTC2311 on the dc2425a. if a true differential signal source is available, apply the signal to the differential inputs j3 and j4; make the fol - lowing changes to the dc2425a: n remove r27, r38. n install 0 0603 resistors at r39, r47. if a single-ended signal source is available, the LTC2311 may be driven differentially by applying the signal to j3. the LTC2311 may be driven in the pseudo-differential bipolar mode by applying the single-ended signal to j3; make the following changes to the dc2425a: n move jp5 to the bip position. n install a 10f 0603 capacitor at c56. the LTC2311 may be driven in the pseudo-differential unipolar mode by applying the single-ended signal to j3; make the following changes to the dc2425a: n move jp5 to the uni position. n install a 10f 0603 capacitor at c56. quick s tart p roce d ure dc2425af demo manual dc2425a
4 signal connection s j1 fpga program: factory use only. j2 jtag: factory use only. j3 ain+ input: in the single-ended configuration, this is the signal input. for differential operation, this serves as the positive signal input. j4 ainC input: this input is used only for differential operation. it serves as the negative signal input. j5 clk: this input has a 50 termination resistor, and is intended to be driven by a low jitter 10dbm sine or square wave. to achieve the full ac performance of this part, the clock jitter should be kept under 2ps. this input is capacitively coupled so that the input clock can be either 0v to 2.5v or 1.25v . this eliminates the need for level shifting. to run at the maximum conversion rate, apply the frequency specified in the table 1. jp1 vccio: use this jumper to select the vccio supply voltage. the default setting is 2.5v. the 1.8v setting selects a 1.8v supply voltage. jp2 vdd: use this jumper to select the vdd supply volt - age. the default setting is 5v. the 3.3v setting selects a 3.3v supply voltage. jp3: use this jumper to select the reference source for the LTC2311 . the default setting is drive refout. this setting uses the voltage applied to pin 3 of the LTC2311 as the reference voltage. the ext setting will accept a voltage applied to e11 as the reference voltage. if no volt - age is applied to e11 , the LTC2311 will use it's internal reference, which is 4.096v. jp4 +in coupling: use this jumper to select ac- or dc- coupling of the signal applied to j3. the default setting is dc . at very low input frequencies, using ac-coupling may degrade the distortion performance. jp5 mode: use this jumper to select the signal input mode for the LTC2311. the default setting is diff. the diff setting accepts a single-ended signal from j3 but applies it as a differential signal to the LTC2311. the bip setting accepts a single-ended signal from j3 and applies it as a single-ended bipolar signal to the LTC2311. the uni setting also accepts a single-ended signal from j3 , and applies it as a unipolar signal to the LTC2311. see drive options section fro more details. jp6 C in coupling: use this jumper to select ac- or dc- coupling of the signal applied to j4. the default setting is dc . at very low input frequencies, using ac-coupling may degrade the distortion performance. jp7 cm: use this jumper to set the dc bias point for the signal applied to j3 when jp4 (+in coupling) is in the ac position. the default setting is 4.096v which sets the common mode voltage at 2.048v. the ext setting allows the use of an externally applied common mode voltage applied at e12 (ext_cm1). jp8 data out: use this jumper to select the data output format from the LTC2311. the default setting is cmos. the output data will not be valid if the jumper is moved to the lvds position unless the following changes have been made: install 100 0402 resistors at r26, 75, 76, 99 reprogram the cpld through j1 using the program - ming file LTC2311.pof found at: http ://www .linear.com/demo/dc2425a move jp8 to the lvds position. jp9 eeprom : factory use only. jp10 osc: use this jumper to enable the onboard encode clock source. the default setting is off. the on setting energizes this source. refer to the dc2425a schematic for additional passive elements required to use the onboard source. h ar d ware s etup dc2425af demo manual dc2425a
