LA7357
Pin Functions
1
CHROMA-IN
Chrominance signal input. This pin can handle burst (or unmodulated
carrier for SECAM input) signal amplitudes of between 50 and 800 mVp-p.
2
HPF.MONI
High-pass filter output monitor
To avoid interference between pin 1 and pin 3, this pin should be
connected to VCC during normal operation.
3
FILTER
Phase comparator output
This signal is smoothed with an external capacitor.
The smoothed level will be:
2.0 V or lower for PAL
3.5 V or higher for SECAM or MESECAM.
4
GND
5
SYNC+BGP
BGP + SYNC input
The input level is a 1.0- to 2.0-V rising pulse (
) during the SYNC period,
and a 3.0- to 4.5-V rising pulse (
) during the BGP period. Note that since
a combined BGP and C.SYNC pulse (
) is output from the Y/C IC when
the LA7357 is used in combination with a Sanyo single-chip Y/C IC (any
one of the LA7430, LA7435, or LA71520) no external component will be
required on pin 5.
6
DET-ADJ
7
VCC
Discrimination sensitivity adjustment pin
The discrimination is shifted towards PAL as the pin voltage is increased,
and towards SECAM as the pin voltage is lowered.
This pin is normally left open.
