Input
COMMUNICATION SIGNAL INPUT
Please refer to the Input Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
GSPI serial data in/test data in.
In JTAG mode (JTAG/HOST = HIGH), this pin is used to shift test data
into the device.
In host interface mode, this pin is used to write address and
configuration data words into the device.
Analog Input Decoupling for internal SDI termination resistors.
Input
COMMUNICATION SIGNAL INPUT
Please refer to the Input Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
Chip select / test mode start.
In JTAG mode (JTAG/HOST = HIGH), this pin is Test Mode Start, used
to control the operation of the JTAG test.
In host interface mode (JTAG/HOST = LOW), this pin operates as the
host interface chip select and is active LOW.
Input
COMMUNICATION SIGNAL INPUT
Please refer to the Input Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
Serial data clock signal.
In JTAG mode (JTAG/HOST = HIGH), this pin is the JTAG clock.
In host interface mode (JTAG/HOST = LOW), this pin is the host
interface serial bit clock.
All JTAG/host interface addresses and data are shifted into/out of
the device synchronously with this clock.
Output
PARALLEL DATA BUS
Please refer to the Output Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
20-bit mode
20bit/10bit = HIGH
SMPTE mode (SMPTE_BYPASS = HIGH
and DVB_ASI = LOW):
Chroma data output for SD and HD
data rates; Data Stream 2 for 3G data
rate
DVB-ASI mode (SMPTE_BYPASS = LOW
and DVB_ASI = HIGH):
Not defined
Data-Through mode (SMPTE_BYPASS =
LOW and DVB_ASI = LOW):
Data output
10-bit mode
20bit/10bit = LOW
Forced LOW
Input
CONTROL SIGNAL INPUT
Please refer to the Input Logic parameters in the DC Electrical
Characteristics table for logic level threshold and compatibility.
When this pin is LOW, the serial digital output is the buffered
version of the input serial data. When this pin is HIGH, the serial
digital output is the reclocked version of the input serial data.
