Monolithic Linear IC
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
