The BU9321BKS is a servo signal processor for CD players that incorporates a double-speed, no-adjustment PLL, program servo, and signal processing block on one chip. It operates off a low power supply voltage, and has low power consumption.
Typical Application |
Features |
| ·Portable CD players, radio cassette players, and minicomponent systems | ` 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 DAC is output by the MSB first 2'SCOMP serial out, and offset circuit ON and OFF can be controlled for CD-ROM compatibility.` 16 kilobits of on-chip SRAM absorb ±4 frames of jitter.` Double-speed playback is possible. |
