Description
Mutes the DDO0 and/or RCO/DDO1 outputs.
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
output (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.
Most negative power supply connection for the RCO/DDO1 and RCO/DDO1
output driver.
Connect to GND.
Differential Serial Digital Outputs.
Most positive power supply connection for the DDO0/DDO0 output driver.
Connect to 3.3V.
Most negative power supply connection for the DDO0/DDO0 output driver.
Connect to GND.
Differential outputs of the reference oscillator used for monitoring or test
purposes.
Reference crystal input. Connect to the GO1535 as shown in the
Application Circuit on page
Not connected internally.
Most negative power supply connection for the internal charge pump.
Connect to GND.
