VIDEO OVERSAMPLING SMD
FILTERS
OD SERIES
The OD range of video oversampling SMD analogue filters has been designed for use in
conjunction with a half band interpolating/decimating filter such as the TRW2242 or with the many
encoder chips available which employ digital filtering and an output D to A converter. This type of
digital filtering has good attenuation between the frequencies of Fs/4 and 3Fs/4 where Fs is the
Master Clock rate. When the normal clock rate of 27 MHz is used for the luminance channel the
signal can be expected to have insignificant energy between 6.75 MHz and 20.25 MHz.

With reduced analogue filter costs resulting from oversampling techniques, there is an increased
need for manufacturing facilities to avoid the large production costs associated with the presently
available through hole packages. The Faraday OD range of oversampling filters can be used in
surface mount assembly lines allowing vacuum pick up and reflow.
In order to preserve the integrity of the signal these filters have a good amplitude and group delay
characteristics in the passband, similar to the requirements of CCIR601 but due to the above
considerations do not have significant attenuation below 21 MHz.
