DESCRIPTION
I Analog negative supply voltage (ground)
I Analog positive supply voltage
O Full-scale output current bias
I External clock input
I Complementary external clock input
I LVDS positive input, data bits 0 through 13
D13A is most significant data bit (MSB)
D0A is least significant data bit (MSB)
I LVDS negative input, data bits 0 through 13
D13B is most significant data bit (MSB)
D0B is least significant data bit (MSB)
I Digital negative supply voltage (ground)
I High DLL off / Low = DLL on
I Digital positive supply voltage
I/O Internal reference output or external reference input. Requires a 0.1-µF decoupling capacitor to AGND
when used as reference output.
O DAC current output. Full scale when all input bits are set 1. Connect reference side of DAC load
resistors to AVDD
O DAC complementary current output. Full scale when all input bits are 0. Connect reference side of DAC
load resistors to AVDD
I Asynchronous hardware power down input. Active high. Internally pulldown
