Description
The RC6601 is a fully integrated continuous time filter,
designed for various video filtering applications. The
RC6601 approximates the requirements of the CCIR601
standard for digitizing NTSC and PAL video signals. It pro-
vides factory-set pass band ripple of
5.5 MHz with a -40 dB stop band, beginning at 8 MHz.

0.25 dB typical up to
The structure of the filter assures wide dynamic range opera-
tion with low noise and low distortion. The cutoff frequency
is factory set at 5.5 MHz (
±
5% typical). It can be varied over
a range of 250 kHz–10 MHz by a user supplied voltage V
The voltage V
