Integrated PAL comb filter
Preliminary specification
SAA4960
FEATURES
• One chip adaptive PAL comb filter
• Time discrete but continuous amplitude signal
processing with analog interfaces
• Internal delay lines, filters, clock processing and signal
switches
• Alignment-free
• No hanging dots or residual cross colour on vertical
transients
• Few external components.
GENERAL DESCRIPTION
The SAA4960 is an adaptive alignment-free one chip
comb filter compatible with PAL systems and provides
high performance in Y/C separation.
