The DIT4192 is a digital audio transmitter designed for use in both professional and consumer audio applications. Trans- mit data rates up to 192kHz are supported. The DIT4192 supports both software and hardware operation, which makes it suitable for applications with or without a microcontroller. A flexible serial audio interface is provided, supporting stan- dard audio data formats and easy interfacing to audio DSP serial ports.
The DIT4192 digital audio transmitter supports sampling rates up to 192 kHz and complies with AES‑3, IEC‑60958, and EIAJ CP‑1201 interface standards. It can operate in either software mode, using a serial control port, or hardware mode with dedicated control pins, making it suitable for professional and consumer audio applications.
The device is supplied in a TSSOP‑28 package, requires a +5 V core supply and a +2.7 V to Vpp logic supply, and uses a master clock up to 25 MHz to generate the required audio and control clocks. Reset is performed via an active‑low RST pin held low for at least 500 ns.

The DIT4192 supports sampling rates up to 192 kHz.
In software mode the CLKO and CLK1 bits in Control Register 02 set the master clock; in hardware mode the CLKO (pin 5) and CLK1 (pin 4) inputs are used.
The device requires a +5 V core supply (Vpp) and a +2.7 V to Vpp logic supply (Vio).
RST must be held low for a minimum of 500 ns to start the reset sequence.
