SDO_EN/DIS
Non
Synchronous
Input
GS1560A
CONTROL SIGNAL INPUT
Signal levels are LVCMOS/LVTTL compatible.
Used to enable or disable the serial digital output loop-through 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.
NC
GS1561
No Connect.

CD_GND
Power
GS1560A
Ground connection for the serial digital cable driver. Connect to analog
GND.

Output
GS1560A
Serial digital loop-through output signal operating at 1.485Gb/s,
1.485/1.001Gb/s, or 270Mb/s.
The slew rate of these outputs is automatically controlled to meet SMPTE
292M and 259M specifications according to the setting of the SD/HD pin.
NC
GS1561
No Connect.
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.
NOTE: When in slave mode, reset the device after the SD/
HD
input has
been initially configured, and after each subsequent SD/HD data rate
change.
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.
