Pin Functions

PIN I/O DESCRIPTION
NAME NO.
INPUT/REFERENCE
INA_P/N K14, L14 I Analog ADC A differential input signal.
VCM B14 O Output of the analog input common-mode (nominally 1.9 V). A 0.1-μF capacitor to AGND is recommended.
VREF A14 O Reference voltage output (2-V nominal). A 0.1-μF capacitor to AGND is recommended, but not required.
CLOCK/SYNC
CLKINP/N P14, P13 I Differential input clock
SYNCP/N P9, N9 I Synchronization input. Inactive if logic low.
When clocked in a high state initially, this is used for resetting internal clocks and digital logic and starting the SYNCOUT signal. Internal 100-Ω termination.
CONTROL/SERIAL
ENABLE B11 I Chip enable – active high. Power-down function can be controlled through SPI register assignment. Internal 50-kΩ pullup resistor to IOVDD.
SCLK A12 I Serial interface clock. Internal 50-kΩ pulldown resistor.
SDENB A13 I Serial interface enable. Internal 50-kΩ pulldown resistor.
SDIO A11 I/O Bidirectional serial data in 3 pin mode (default). In 4-pin interface mode (register x00, D16), the SDIO pin is an input only. Internal 50-kΩ pulldown.
SDO A10 O Unidirectional serial interface data in 4 pin mode (register x00, D16). The SDO pin is tri-stated in 3-pin interface mode (default). Internal 50-kΩ pulldown resistor.
SRESET B12 I Serial interface reset input. Active low. Initialized internal registers during high to low transition. Asynchronous. Internal 50-kΩ pullup resistor to IOVDD.
TESTMODE B13 — Factory internal test, do not connect

DACLKP/N H2, H1 O DDR differential output data clock for Bus A. Register programmable to provide either rising or falling edge to center of stable data nominal timing.
OVRAP/N M5, L5 O Bus A, Overrange indicator, LVDS output. A logic high signals an analog input in excess of the full-scale range. Optional SYNC output.
