DESCRIPTION
The M65824FP is a CMOS IC for playback of a compact disk (CD-DA).
It is equipped with memory, non-adjustment PLL, 4fs digital filter and D-A converter.
The M65824FP can configure a compact CD-DA system.
FEATURES
•Non-adjustment EFM-PLL with wide lock-range (built-in VCO)
•Jitter margin ± 8 frames
•Operatable CLV servo command
•Attenuation (-12 dB)
•Built-in 4fs digital filter
•Built-in digital de-emphasis circuit
•Built-in D-A converter
•Compact set by the adoption of a compact package
•Built-in analog LPF
•External D-A mode

(3) Operation description
• Microcomputer command read/write
Data (MSD) is read at a rising edge of the clock pulse (MCK).
When a command is determined at a falling edge of the latch line
(MLAB), the data line (MSD) is concurrently switched to the output
mode to output a status requested by data bits D3, D2, D1 and D0.
When the latch line is set to "H", the data line is returned to the
input mode again.
•Status request/interface command
When requesting various types of the M65824FP status, a
microcomputer writes data in D3, D2, D1 and D0 for indicating the
requested status in advance.
After this command is latched, the status is continuously output
while the latch line (MLAB) is set to "L".
