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.
The BU9321BKS is an optical‑disc IC designed for CD players, portable CD players, radio cassette players and mini‑component systems. It combines a double‑speed, no‑adjustment PLL, program servo and signal‑processing blocks on a single chip, operating from a low power supply voltage.
Key features include on‑chip PLL, frame‑synchronizing detection, servo filters for focus, tracking and sled, sub‑code serial output, CLV and track‑jump sequencers, de‑interleave function, error detection/correction, and 16 kilobits of on‑chip SRAM. The device supports double‑speed playback and provides both P‑code and Q‑code output pins.
