RF SIGNAL PROCESSOR
S5L1462B
1
INTRODUCTION
The S5L1462B01 is used for CD and DVD playback. It receives optical signal
from the optical pick-up to produce the data-generating RF signal, the servo
error signal for stable servo control, and the monitor signal. This RF IC can be
used in the CD 1x, 2x, or the DVD 1x CLV (Constant Linear Velocity) mode.
The DVD mode is compatible with the Single/Dual Layer disc. The CD mode is
compatible with the CD-ROM, CD-R and CD-RW disc.
FEATURES
Can be used with CD 1x, 2x, and DVD 1x playback mode.
Able to input and handle all optical signal of the CD-R's P/U.
Built-in pre-amp with adjustable gain, compatible with various P/U.
Built-in AGC (Automatic Gain Control) circuit operated by light detection feedback.
Built-in RF AMP & Equalizer compatible with CD 1x, 2x, and DVD 1x.
Built-in Astigmatism Method FE (Focus Error) AMP for CD and DVD use.
Built-in 3-BEAM TE (Tracking Error) AMP for CD.
Built-in 1-BEAM DPD (Differential Phase Detector) TE AMP for DVD.
Built-in RF mirror detection circuit for CD and DVD.
Built-in RF defect detection circuit for CD and DVD.
Built-in FOK (Focus O.K.) signal detection circuit for CD and DVD.
Built-in RF envelope signal generating circuit for CD and DVD.
Built-in interrupt defect detection circuit.
Built-in ALPC (Automatic Laser Power Control) circuit for CD and DVD.
Built-in standard voltage generating circuit for analog circuit use (2.5V, 1.65V).
Built-in defective waveform detection circuit.
Power operating range: 4.5
5.5 V, 3.0
3.6 V.
80 PIN, QFP.
