G8
FIFO_LD
Synchronous
with PCLK
Output
CONTROL SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Used as a control signal for external FIFO(s).
Normally HIGH but will go LOW for one PCLK period at SAV.
H2
TERM2
Analog
Input
Termination for serial digital input 2. AC couple to PDBUFF_GND.
H4
CS_TMS
Synchronous
with
SCLK_TCK
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Chip Select / Test Mode Select
Host Mode (JTAG/HOST = LOW)
CS_TMS operates as the host interface chip select,
CS
,
and is active
LOW.
JTAG Test Mode (JTAG/HOST = HIGH)
CS_TMS operates as the JTAG test mode select, TMS, and is active
HIGH.
NOTE: If the host interface is not being used, tie this pin HIGH.
H5
SCLK_TCK
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Serial Data Clock / Test Clock.
Host Mode (JTAG/HOST = LOW)
SCLK_TCK operates as the host interface burst clock, SCLK. Command
and data read/write words are clocked into the device synchronously with
this clock.
JTAG Test Mode (JTAG/HOST = HIGH)
SCLK_TCK operates as the JTAG test clock, TCK.
NOTE: If the host interface is not being used, tie this pin HIGH.
H6
SDOUT_TDO
Synchronous
with
SCLK_TCK
Output
CONTROL SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
Serial Data Output / Test Data Output
Host Mode (JTAG/HOST = LOW)
SDOUT_TDO operates as the host interface serial output, SDOUT, used
to read status and configuration information from the internal registers of
the device.
JTAG Test Mode (JTAG/HOST = HIGH)
SDOUT_TDO operates as the JTAG test data output, TDO.
H7
DATA_ERROR
Synchronous
with PCLK
Output
STATUS SIGNAL OUTPUT
Signal levels are LVCMOS/LVTTL compatible.
The DATA_ERROR signal will be LOW when an error within the received
data stream has been detected by the device. This pin is a logical 'OR'ing
of all detectable errors listed in the internal ERROR_STATUS register.
Once an error is detected, DATA_ERROR will remain LOW until the start
of the next video frame / field, or until the ERROR_STATUS register is
read via the host interface.
The DATA_ERROR signal will be HIGH when the received data stream
has been detected without error.
NOTE:
It is possible to program which error conditions are monitored by
the device by setting appropriate bits of the ERROR_MASK register HIGH.
All error conditions are detected by default.
