Luma and Chroma Signals are added together to make up the
Composite Video Signal. All timing signals are controlled.
The YCrCb data is also used to generate RGB data with appropri-
ate sync and blank levels. The YUV levels are scaled to output
the suitable SMPTE/EBU N10, MII, or Betacam levels.
Each DAC can be individually powered off if not required. A
complete description of DAC output configurations is given in
the MR2 Bit Description section.
Video output levels are illustrated in Appendix 9.

Passband ripple is defined to be fluctuations from the 0 dB response in the passband, measured in (dB). The
3 dB bandwidth refers to the –3 dB cutoff frequency.
Passband ripple is defined to be fluctuations from the 0 dB response in the passband, measured in (dB). The
3 dB bandwidth refers to the –3 dB cutoff frequency.
passband is defined to have 0-fc frequency limits for a low-pass filter, 0–f1 and f2–infinity for a notch filter,
where fc, f1, f2 are the –3 dB points.

INTERNAL FILTER RESPONSE
The Y Filter supports several different frequency responses
including two low-pass responses, two notch responses, an
Extended (SSAF) response with or without gain boost/attenuation,
a CIF response and a QCIF response. The UV Filter supports
several different frequency responses including five low-pass
responses, a CIF response and a QCIF response, as can be seen on
the following pages.
In Extended Mode there is the option of twelve responses in
the range from –4 dB to +4 dB. The desired response can be
chosen by the user by programming the correct value via the
I
following pages. For more detailed plots refer to AN-562
Analog Devices’ Application note.
