Bt864A/865A
Flexible Operation for
a Wide Range of Video Systems
High-performance video combined with the right set
of features make the Bt864A/865A a versatile device
for almost any video system. 10-bit DACs provide the
high-resolution video required for modern satellite
set-top boxes, DVD players, PC add-in cards, video
conferencing systems and digital cameras. Several
power conservation modes extend portable system
battery life and help to reduce system heating.
New televisions and media, which make use of
wide screen 16:9 aspect ratios, are also supported
by the Bt864A/865A to provide the best flexibility,
performance and functionality.

Functional block diagram
The Bt864A/865A accepts video data in a variety
of ways: CCIR 601, NTSC, and PAL square pixel
formats. This provides system designers with
maximum flexibility. Either 3.3V or 5V operation
is possible with the Bt864A/865A to permit operation
within any system environment. Horizontal sync
and vertical sync may be configured as inputs
(slave mode) or outputs (master mode). In addition
to the normal blanking which occurs during Hsync
and Vsync, blanking may be externally controlled
during active video. The rise and fall times of sync,
the burst envelope, and closed caption data are
internally controlled.
