? Advanced jitter attenuating PLL with low intrinsic period jitter of 50 ps RMS.

? S/PDIF recovered clock using PLL, or stand alone crystal derived clock generation.

? Supports 10 – 27MHz crystal clock frequencies.

? 2-wire / 3-Wire serial or hardware control interface.

? Programmable Audio data interface modes:

- I2S, Left, Right Justified or DSP

- 16/20/24 bit word lengths

? 8 channel receiver input and 1 channel transmit output.
