Description
Serial digital differential input 0.
Center tap of two 50Ω on-chip termination resistors between DDI0 and DDI0.
Recommended connect to GND.
Serial digital differential input 1.
Center tap of two 50Ω on-chip termination resistors between DDI1 and DDI1.
Serial digital differential input 2.
Center tap of two 50Ω on-chip termination resistors between DDI2 and DDI2.
Serial digital differential input 3.
Center tap of two 50Ω on-chip termination resistors between DDI3 and DDI3.
Serial digital input select.
Bypass the reclocker stage.
When BYPASS is HIGH, it overwrites the AUTOBYPASS setting.
Automatically bypasses the reclocker stage when the PLL is not locked
This pin is ignored when BYPASS is HIGH.
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.
Most positive power supply connection for the internal VCO section.
Connect to 3.3V.
Most negative power supply connection for the internal VCO section.
Connect to GND.
