MITSUBISHI LINEAR INTEGRATED CIRCUIT
M52325AP
SECAM DECODER
[GENERAL DESCRIPTION]
pin configuration
The M52325AP is designed for SECAM chrominance
decoding.The IC should preferably be used in conjunction
with PAL / NTSC signal processor M52340SP and the
switched capacitor baseband delay line.
It consists of a bell filter,a demodulator and an identification
fref / IDENT 1
BELL OUT 2
circuit. The IC needs no adjustment and few external
Vcc 3
components are required. A signal with highly stable
reference frequency is required for the calibration, and
BAND GAP 4
a three - level sandcastle pulse for blanking and burst gating. SACAM KILLER OUT 5
