3.3 V Digital Power pin(s).
Digital Ground pin(s).
Serial Port Data Clock pin. The serial data CLOCK for the serial port.
Function
14-Bit Parallel Data Bus for I and Q Data. The required numeric format is twos complement with D13
as the sign bit and D12–D0 as the magnitude bits. Alternating 14-bit words are demultiplexed onto
the I and Q data pathways (except when operating in the interpolating DAC mode, in which case
every word is routed onto the I data path). When the TxENABLE pin is asserted high, the next
accepted word is presumed to be I data, the next Q data, and so forth.
Profile Select Pin 1. The LSB of the two profile select pins. In conjunction with PS0, selects one of four
profile configurations.
Profile Select Pin 0. The MSB of the two profile select pins. In conjunction with P1, selects one of four
profile configurations.
Serial Port Chip Select pin. An active low signal that allows multiple devices to operate on a single
serial bus.
Serial Port Input/Output Data pin. Bidirectional serial DATA pin for the serial port. This pin can be
programmed to operate as a serial input only pin, via the control register bit 00h<7>. The default
state is bidirectional.
Serial Port Output Data pin. This pin serves as the serial data output pin when the SDIO pin is
configured for serial input only mode. The default state is three-state.
Serial Port Synchronization pin. Synchronizes the serial port without affecting the programmable
register contents. This is an active high input that aborts the current serial communication cycle.
No connect.
