AK4364 Datasheet | Asahi Kasei Microdevices

DESCRIPTION The AK4364 is a stereo CMOS D/A Converter and Phase Locked Loop for use in digital video broadcast set-top box applications or DVD. The DAC signal outputs are single-ended and are analog filtered to remove out of band noise. Therefore no external filters are required. The PLL provides selectable sampling clock frequencies locked to the 27MHz recovered MPEG clock. The AK4364 has also Digital Audio Interface Transmitter.
