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.
