Digital audio data transmitter suits consumer apps

The AK4104 digital audio interface transmitter from AKM Semiconductor claims to offer lower cost and smaller size than previous devices, suiting it for consumer applications. The 24-bit 192-kHz device encodes and transmits audio data according to the AES3, IEC60958, S/PDIF and EIAJ CP1201 standards.

Master clock frequencies up to 1536fs are supported, and control is through a three- or a four-wire serial interface. In three-wire control mode, a two-input selector is available, as is a through mode.

The AK4104 supports sampling rates from 8 kHz to 192 kHz with an integrated 42-bit channel status buffer. Operation is from +3.3 V at 3 mW.

The AK4104 is packaged in a 16-pin TSSOP. Samples and an evaluation board are available now.
