AK4364

96kHz 24Bit ∆Σ DAC with PLL and DIT

GENERAL 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.
