BYPASS
Logic Input
Bypass the reclocker stage.
When BYPASS is HIGH, it overwrites the AUTOBYPASS setting.
20
AUTOBYPASS
Logic Input
Automatically bypasses the reclocker stage when the PLL is not locked
This pin is ignored when BYPASS is HIGH.
21
AUTO/MAN
Logic Input
Auto/Manual select.
When set HIGH, the standard is automatically detected from the input data
rate. When set LOW, the user must program the input standard using the
SS[2:0] pins.
22
VCC_VCO
Power
Most positive power supply connection for the internal VCO section.
Connect to 3.3V.
23
VEE_VCO
Power
Most negative power supply connection for the internal VCO section.
Connect to GND.
