Rev. C

1) Bt815 pin definitions changed to provide complete compatibility
between Bt819, Bt817 and Bt815 (Pin numbers 64, 67, 74 and
81).
2) Bt817 pin definition for pin 81 changed to provide compatibility
between Bt819, Bt817 and Bt815.
3) Standard Crystal included in recommended crystal manufacturers
as they offer very short lead times.
4) Bias capacitors changed to optional. Not recommended for new
designs.
5) FIFO pin definitions in Table 7 and Table 9 are incorrect. The even
field is field 2, and the odd field is field 1.
6) API mode-A change: CLKIN must be connected to CLKx1.
7) API mode-B change: The FIFO should not be emptied while active
video is being written into the FIFO. Do not read the FIFO until
empty, during the active video line.
8) In both API modes A and B: The control codes are not valid when
the FIFO is not being read.
9) Example schematic in Figure 36 changed to reflect Bt819A.
10) Typographical error in the STATUS register corrected. COF is the
least significant bit.
11) Additional crystal vendors added. Short lead times available from
Standard Crystal.
12) The timing from QCLK to Data Valid in 8-bit mode was changed.
See Figure 37.
13) The VPOLE register definition was changed to indicate that
DVALID, FIELD and AFF do not have programmable polarities in
API mode.
