Clock Pins (XIN and XOUT)
The Router 5000 chip requires a 10 MHz external crystal or oscillator to provide
its input clock signal. The chip then multiplies the input frequency by an amount
specified in the device’s hardware template (specified during device development
using the NodeBuilder FX Development Tool; see NodeBuilder Hardware
Template on page 53) to derive its internal system clock frequency. For
