Description
Loss of Signal.
Set HIGH when there are no transitions on the active DDI[3:0] input.
Most positive power supply connection for the internal glue logic.
Connect to 3.3V.
Most negative power supply connection for the internal glue logic.
Connect to GND.
This signal will be set HIGH when the reclocker has locked to 270Mbps or LOW
when a non-SMPTE standard is applied. (i.e. the device is not locked).
Controls the loop bandwidth of the PLL.
Serial clock or secondary data output mute.
Assert LOW for reduced power consumption, see
Characteristics.
When RCO_MUTE = LOW, the RCO/DDO1 output is powered down.
When RCO_MUTE = HIGH, the RCO/DDO1 output is active.
NOTE: This is not a logic input pin.
Mutes the DDO0 and/or RCO/DDO1 outputs.
DDO_MUTE
NOTE:
MUTE = Outputs latched at previous data bit.
Power down = Outputs pulled to V
Data/Clock select.
When set HIGH, the RCO/DDO1 pin will output a copy of the serial digital ouput
(DDO0).
When set LOW, the RCO/DDO1 pin will output a re-timed clock (RCO).
Serial clock or secondary data output.
When RCO_MUTE is connected to VCC, the serial digital differential clock or
secondary data output will be presented.
Do not connect.
Most positive power supply connection for the RCO/DDO1 and RCO/DDO1
output driver.
Connect to 3.3V.
