PRODUCT SPECIFICATION
TMC22x5y
5
P
processed as chrominance to find the magnitude and phase of
the chrominance vector. These three components are then
compared across the (0H & 1H) and (1H & 2H) taps of the
comb filter to produce the difference in luminance, chromi-
nance magnitude, and chrominance phase. These differences
are then translated in the user-programmable lookup table to
produce the “K” signal which controls the complementary
mix between the output of the comb filter and the simple
bandsplit decoder. That is, the “K” signals controls how
much of the combed high frequency luminance signal is sub-
tracted from the simple bandsplit chrominance for chroma
combs, or added to the low frequency output of the bandsplit
for luma comb filters.
Output Processor
The demodulated chrominance signal and the luminance
signal are passed through a programmable output matrix,
producing RGB, YUV, or YC
B
C
R
. When the clock is at
27MHz, a D1 signal can be produced on the R/V output with
the embedded TRS words fixed to the external HSYNC and
VSYNC timing.
Parallel and Serial Microprocessor Interfaces
The parallel microprocessor interface employs 12 pins, the
serial port uses 5. A single pin, SER, selects between the two
interface modes.
In parallel interface mode, one address line is decoded for
access to the internal control register and its pointer.
Controls are reached by loading a desired address through
the 8-bit D
7-0
port, followed by the desired data (read or
write) for that address. The control register address pointer
auto-increments to address 3Fh and then remains there.
A 2-line serial interface may also be used for initialization
and control. The same set of registers accessed by the paral-
lel port is available to the serial port. The device address in
the serial interface is selected via pins SA
2-0
.
The RESET pin sets all internal state machines to their ini-
tialized conditions and places the decoder in a power-down
mode. All register data are maintained while in power-down
mode.
