BU9314KS General Description


The BU9314KS is a servo signal processor for CD players that incorporates a double-speed, no-adjustment PLL, program servo, and signal processing block, and D / A converter on one chip. It operates off a low power supply voltage, and has low power consumption.

BU9314KS Features

` PLL on chip. Bit clock extraction possible with just a few external components. EFM data modulation is possible.
` Frame synchronizing signal detection and protection.
` Servo filters for focus, tracking, and sled are on chip. Characteristics can be controlled using commands from the controller.
` Sub-code serial output pin provided.
` Output pins for both P-code and Q-code.
` CLV sequencer automatically determines the CLV mode.
` Track jump sequencer on chip. Possible to jump any number of tracks.
` De-interleave function, and 2-level error detection, correction and flag processing for C1 and C2.
` The signal to the D / A converter is output by the MSB first 2'SCOMP serial out, and offset circuit ON and OFF can be controlled for CD-ROM compatibility.
` 16k bits of on-chip SRAM absorb ±4 frames of jitter.
` Double-speed playback is possible.
` Built-in 8Fs digital filter and 16-bit D / A converter.
` Built-in digital de-emphasis function.

BU9314KS Typical Application

·Portable CD players, radio cassette players, and minicomponent systems.
