UPD63711 Description
PRELIMINARY PRODUCT INFORMATION MOS INTEGRATED CIRCUIT µPD63711 PACT DISC DIGITAL SERVO/DATA PROCESSOR WITH ON-CHIP RF AMPLIFIER The µPD63711 is an LSI that has all of the functions required to control a CD player, with a digital servo, data .. processor, RF amplifier, audio DAC, and post-processing filter incorporated on a single chip. CD-TEXT is also supported.
UPD63711 Key Features
- Realization of set miniaturization by integrating a digital servo, data processor, 8-fs oversampling digital filter, D/A
- On-chip SCF (Switched Capacitor Filter) as audio DAC block post-processing filter
- Employment of digital loop filter for four servo systems. Since the filter coefficient is programmable, a variety of cha
- On-chip automatic adjustment function. Automatic adjustments of focus offset, focus gain, focus balance, tracking offset
- On-chip 16-Kbit SRAM needed for de-interleaving
- Since a digital PLL circuit is employed, the external ponents of the bit clock regeneration circuit are not needed
- CIRC error correction capability C1: Double correction C2: Quadruple correction (CD-ROM mode)
- On-chip fourth order ∆Σ type one-bit D/A converter and post-processing filter
- On-chip mirror circuit, DEFECT circuit, RFOK circuit, and EFM parator
- A de-emphasis circuit can be controlled via a microcontroller for supporting connection with shock-proof ICs
