Time Division Multiplex Data Interface
Positive power supply, nominally + 5 V.
Negative power supply, nominally ground.
Positive power supply for analog circuits, nominally + 5 V.
Negative power supply for analog circuits, nominally ground.
Positive power supply for input and output circuits, nominally + 5 V.
Negative power supply for input and output circuits, nominally ground.
Connection for internal 3 V regulator decoupling capacitor.
Hardware reset when at a logic low, normal operation when at a logic high. This pin has a
Schmitt trigger input.
Hardware selection of LT (logic low) and NT (logic high) operating mode.
MCU mode versus GCI mode select input.
Parallel versus serial control port selection. PAR/SER = 1 (logic high) for a parallel port.
PAR/SER = 0 (logic low) for serial control port interfacing.
Master/Slave mode select input for the IDL2 or GCI interface.
Master mode for M/S = 1 (logic high).
The MCU 8 kHz frame sync for data transmitted on the D out pin.
In GCI operation, this pin serves as the FSC pin.
The MCU 8 kHz frame sync for data input to the D in pin.
This pin is not used in GCI mode.
MCU bit clock, or GCI 2x bit clock.
Serial data out of MCU or GCI interface.
Serial data into MCU or GCI interface.
