Texas Instruments  DS90UA101TRTVRQ1

The DS90UA101-Q1 Serializer, in conjunction with the DS90UA102-Q1 Deserializer, provides a solution for distribution of digital audio in multi-channel audio systems. It transmits a high-speed serialized interface with an embedded clock over a single shielded twisted pair or coaxial cable. The serial bus scheme supports high speed forward data transmission and low speed bidirectional control channel over the link. Consolidation of digital audio, general-purpose IO, and control signals over a single differential pair reduces the interconnect size and weight, while also reducing design challenges related to skew and system latency.

The DS90UA101-Q1 Serializer embeds the clock and level shifts the signals to high-speed low-voltage differential signaling. The device serializes up to eight digital audio data inputs, word/frame sync, bit clock, and system clock.

Four dedicated general purpose input pins and four general purpose output pins allow flexible implementation of control and interrupt signals to and from remote devices.
