Other SerDes Signals
Pin Name: XTALO
Pin Number: 21
Crystal oscillator pin for SerDes reference clock. A 25MHz crystal must be used.
Pin Name: XTALI/CLKI
Pin Number: 22
Crystal oscillator pin for SerDes reference clock. When external clock source is selected, the external clock
(either 25MHz or 100 MHz) will come in through this pin. The clock must be 1.8V swing and the precision
requirement is ±100ppm.
Pin Name: REXT
Pin Number: 24
External reference resistor pin for termination calibration. This pin provides the additional function of selecting
frequency of the clock source. For 25MHz, a 1K, 1% resistor is connected to ground. For 100MHz, a 4.99K, 1%
resistor is connected to ground.
