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.
