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 functions for NTSC colour-difference
signals to suppress cross-colour.
