7 / 46 page VDR DR GND + - + - ADC08500 www.ti.com SNAS373E – MAY 2007 – REVISED APRIL 2013 PIN DESCRIPTIONS AND EQUIVALENT CIRCUITS (continued) Pin Functions Pin No. Symbol Equivalent Circuit Description Out Of Range output. A differential high at these pins indicates that the differential input is out of range (outside the range 79 OR+ ±VIN/2 as programmed by the FSR pin in non-extended control 80 OR- mode or the Input Full-Scale Voltage Adjust register setting in the extended control mode). Differential Clock outputs used to latch the output data. Delayed and non-delayed data outputs are supplied synchronous to this 82 DCLK+ signal. This signal is at 1/2 the input clock rate in SDR mode 81 DCLK- and at 1/4 the input clock rate in the DDR mode. The DCLK outputs are not active during a calibration cycle, therefore this is not recommended as a system clock. 2, 5, 8, 13, 16, 17, 20, VA Analog power supply pins. Bypass these pins to ground. 25, 28, 33, 128 40, 51 ,62, Output Driver power supply pins. Bypass these pins to DR 73, 88, 99, VDR GND. 110, 121 1, 6, 9, 12, 21, 24, 27, GND Ground return for VA. 41 42, 53, 64, 74, 87, 97, DR GND Ground return for VDR. 108, 119 22, 23, 29, 36–39, 43–50, 52, 54–61, 63, NC No Connection. Make no connection to these pins. 65–72, 75–78, 98, 109, 120 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
