1H Delay Line for PAL Systems
LC89950
Overview
The LC89950 is an IC that provides 1H delay processing
for color difference signals used in PAL and SECAM
format TV. The LC89950 has two CCD systems, one for
the R-Y and one for the B-Y signal, and drives these
CCDs with a 4-MHz clock generated within the IC. It uses
a sandcastle-shaped three-value input clock with a 1 H (64
μs) period.
Features
5-V single-voltage power supply
Two input and output systems, one each for R-Y and B-
Y signals
Takes a sandcastle pulse (SCP) as the input clock, and
converts that to a burst gate pulse (BGP) signal
internally.
Generates the CCD drive pulses (4 MHz) from the input
clock using a PLL circuit.
Uses BGP as clamp pulses and clamps the no signal
section (back porch) once every horizontal scan period.
The output signal is in-phase with the input signal
