LV1605M ^{Analog Signal Processor for CD Players}
Overview
The LV1605M implements the analog signal processing and servo control required by compact disc players, and, when
combined with a CD DSP such as the LC78604E or LC78605E, can implement a CD player with a minimal parts count.
The LV1605M also provides a gain switching pin to allow it to support playback of CD-RW discs.
Functions
IV amplifier, RF amplifier (with AGC and hold function on defect detection), APC, FE (with VCA), TE (with VCA and
auto-balance), focus servo amplifier (with offset canceller and hold function on defect detection), tracking servo
amplifier (with offset canceller and hold function on defect detection), spindle servo amplifier (with gain switching
function and hold function on defect detection), sled servo amplifier (with on/off function and hold function on defect
detection), focus detection (DRF and FZD), track detection (HFL and TES), defect detection, shock detection, and disc
mode gain switching function.
Features
• The LV1605M provides the following automatic adjustment functions.
— Focus offset, auto canceller: FE (pin 21)
— Tracking offset, auto canceller: TE (pin 7)
— E/F balance automatic adjustment
— RF level AGC function
— Tracking servo gain RF level following function
— Focus servo gain RF level following function
• Focus search smoothing setting pin: FSC (pin 58)
• Focus search mode switching pin: FSS (pin 54)
• Play disc mode (normal or CD-RW) switching pin: RW (pin 44)
