Description
Ground connection for all power domains. Exposed pad
Digital and I/O-ring pre driver supply voltage, 1.8V
Common Mode voltage output
Analog supply voltage, 1.8V
Analog input (non-inverting, inverting)
Clock circuitry supply voltage, 1.8V
Clock input, non-inverting (format: LVDS, LVPECL, CMOS/TTL, Sine Wave)
Clock input, inverting. For CMOS input on CLKP, connect CLKN to ground
CLK_EXT signal enabled when low (zero). Tristate when high.
Data format selection. 0: Offset Binary, 1: Two's Complement
Full chip Power Down mode when Low. All digital outputs reset to zero. After chip power up
always apply Power Down mode before using Active Mode to reset chip.
Output Enable. Tristate when high
I/O ring post-driver supply voltage. Voltage range 1.7 to 3.6V
