LA9200NM, LA9201M
Analog Signal Processors
for Compact Disc Players
OVERVIEW
The LA9200NM and LA9201M arc bipolar, analog
signal processors for use in compact disc players. They
incorporate all focusing and tracking control circuits for
a complete servo-controlled, three-beam tracking
system.
The LA9200NM and LA9201M can be combined with
either an LC7860K or LC7863K digital signal proces-
sor, an LC7881 serial input digital-to-analog converter
and a minimum of external components to form a
complete compact disc player.
The LA9200NM and LA9201M operate either from a
5 V single-ended supply or from a ±5 V dual supply,
and are available in 48-pin QIPs.

FUNCTIONAL DESCRIPTION
RF Summing Amplifier
The combined current from photodiodes A and C,
(A + C), is input on FIV1, and the combined current
from B and D, (B + D), on FIV2. These signals are
currenMo-voltage converted and then input to the RF
summing amplifier as shown in figures 1 and 2. The
summing amplifier output, (A + C) + (B + D) on RFSM,
is filtered externally to generate the HF (eye pattern)
signal. Note that the output voltage on RFSM should be
between 1 and 2 V„.D.
