F3
DETECT_TRS
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select external HVF timing mode or TRS Extraction timing
mode.
When DETECT_TRS = LOW, the device will use timing from the
externally supplied H:V:F or CEA-861 timing signals, dependent on the
state of the TIM_861 pin.
When DETECT_TRS = HIGH, the device will extract timing from TRS
signals embedded in the supplied video stream.
F4
RSV
Reserved. Do not connect.
F10
RSET
Analog
Input
An external 1% resistor connected to this input is used to set the
SDO/SDO output amplitude.
G1, H10
IO_VDD
Non
Synchronous
Input
Power
Power supply connection for digital I/O buffers. Connect to +3.3V or
+1.8V DC digital.
G2, H9
IO_GND
Non
Synchronous
Input
Power
Ground connection for digital I/O buffers. Connect to digital GND.
G3
TIM_861
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select external CEA-861 timing mode.
When DETECT_TRS = LOW and TIM_861 = LOW, the device will use
externally supplied H:V:F timing signals.
When DETECT_TRS = LOW and TIM_861 = HIGH, the device will use
externally supplied HSYNC, VSYNC, DE timing signals.
When DETECT_TRS = HIGH, the device will extract timing from TRS
signals embedded in the supplied video stream.
G4
20bit/10bit
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select the input data bus width.
G5
DVB_ASI
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
When set HIGH, the device is configured for the transmission of
DVB-ASI data in SD mode (SD/HD = HIGH).
When set LOW, the device will not support the encoding of DVB-ASI
data.
NOTE: When operating in DVB-ASI mode the SD/HD pin must be set
HIGH and SMPTE_BYPASS must be set LOW.
