SMPTE_BYPASS
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
When set HIGH in conjunction with DVB_ASI = LOW, the device
will be configured to operate in SMPTE mode. All I/O processing
features may be enabled in this mode.
When set LOW, the device will not support the scrambling or
encoding of received SMPTE data. No I/O processing features
will be available.
19
RSET
Analog
Input
Used to set the serial digital output signal amplitude. Connect to
CD_VDD through 281
Ω
+/- 1% for 800mV
p-p
single-ended output
swing.
20
CD_VDD
Power
Power supply connection for the serial digital cable driver.
Connect to +1.8V DC analog.
21
SDO_EN/DIS
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to enable or disable the serial digital output stage.
When set LOW, the serial digital output signals SDO and SDO
are disabled and become high impedance.
When set HIGH, the serial digital output signals SDO and SDO
are enabled.
22
CD_GND
Power
Ground connection for the serial digital cable driver. Connect to
analog GND.
23, 24
SDO, SDO
Analog
Output
Serial digital output signal operating at 270Mb/s.
The slew rate of these outputs is automatically controlled to meet
SMPTE 259M specifications.
25
RESET_TRST
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to reset the internal operating conditions to default settings
and to reset the JTAG test sequence.
Host Mode (JTAG/HOST = LOW)
When asserted LOW, all functional blocks will be set to default
conditions and all input and output signals become high
impedance, including the serial digital outputs SDO and
SDO.
Must be set HIGH for normal device operation.
JTAG Test Mode (JTAG/HOST = HIGH)
When asserted LOW, all functional blocks will be set to default
and the JTAG test sequence will be held in reset.
When set HIGH, normal operation of the JTAG test sequence
resumes.
26
JTAG/HOST
Non
Synchronous
Input
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to select JTAG Test Mode or Host Interface Mode.
When set HIGH, CS_TMS, SDOUT_TDO, SDI_TDI and
SCLK_TCK are configured for JTAG boundary scan testing.
When set LOW, CS_TMS, SDOUT_TDO, SDI_TDI and
SCLK_TCK are configured as GSPI pins for normal host
interface operation.
