Product data sheet
2.1 Video acquisition
2.2 Comb filter video decoder
The SAF7115 incorporates a frame locked audio clock generation. This function ensures
that there is always the same number of audio samples associated with a frame, or a set
of fields. This prevents the loss of synchronization between video and audio, during
capture or playback. Furthermore, there is an option to use a second analog onboard PLL
to enhance this audio clock to a low jitter frame locked audio clock.
The SAF7115 is controlled through the I
programming registers and a bit-rate of up to 400 kbit/s. See
description, pin strapping and applications.
