Product Details

Description



Features:

· Two comb filters, using the switched-capacitor technique, for one line delay time (64 ms)
· 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 ms 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 functions for NTSC colour-difference signals to suppress cross-colour.
