Pin Configuration Table 4. Pin Function Descriptions Pin Number Mnemonic I/O Function 20–14, 7–1 D0–D6, D7– D13 I 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. 8–10, 31–33, 73–75 DVDD 3.3 V Digital Power pin(s). 11–13, 28–30, 70–72, 76–78 DGND Digital Ground pin(s). 21 PS1 I Profile Select Pin 1. The LSB of the two profile select pins. In conjunction with PS0, selects one of four profile configurations. 22 PS0 I Profile Select Pin 0. The MSB of the two profile select pins. In conjunction with P1, selects one of four profile configurations. 23 CS I Serial Port Chip Select pin. An active low signal that allows multiple devices to operate on a single serial bus. 24 SCLK I Serial Port Data Clock pin. The serial data CLOCK for the serial port. 25 SDIO I/O 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. 26 SDO O 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. 27 SYNCIO I 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. 34, 41, 51, 52, 57 NC No connect. |
