Product specification
Baseband delay line
FEATURES • Two comb filters, using the switched-capacitor technique, for one line delay time (64 µs) • Adjustment-free application • No crosstalk between SECAM colour carriers (diaphoty) • Handles negative or positive colour-difference input signals • Clamping of AC-coupled input 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 • Addition of delayed and non-delayed output signals • Output buffer amplifiers • Comb filtering functi...
