Description
Servo Signal Processor
Manufacturer
ROHM Co. Ltd.
Datasheet
The BU9314KS is a servo signal processor for CD players that incorporates a double-speed, no-adjustment PLL, pro-
gram 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.
FApplications
Portable CD players, radio cassette players, and mini-
component systems.
