.
A 2470
resistor (for input ranges 64–940 and 64–960, output standards
EIA-770.3) must be connected from this pin to ground and is used to control the
amplitudes of the DAC outputs. For input ranges 0–1023 (output standards
RS-170, RS-343A) the R
SET
value must be 2820
.
Optional External Voltage Reference Input for DACs or Voltage Reference
Output (1.235 V).
This input resets the on-chip timing generator and sets the ADV7197 into Default
Register setting. Reset is an active low signal.
TTL Address Input. This signal sets up the LSB of the MPU address. When this
pin is tied high, the I
2
C filter is activated which reduces noise on the I
2
C interface.
When this pin is tied low, the input bandwidth on the I
2
C interface is increased.
10-Bit HDTV Input Port for Color Data. In 4:2:2 mode the multiplexed CrCb
data must be input on these pins. B data input in RGB mode.
