Product specification
Baseband delay line
FEATURES • Two delay lines, using the switched-capacitor technique, for a delay time of one horizontal line (1H) minus 55 ns (64 µs − 55 ns) • Adjustment-free application • Handles negative or positive colour-difference input signals • Clamping of AC-coupled input signals [mostly colour-difference signals ±(R−Y) and ±(B−Y)] • VCO without external components • 3 MHz internal clock signal derived from a 6 MHz CCO, line-locked by the sandcastle pulse (64 µs line) • Sample-and-hold circuits and low-pass filters to suppress the 3 MHz clock signal • Output buffer amp
