Transmitter CLKIN Input Clock
An external low jitter clock may be supplied at pin 2 of jumper J1 or alternatively,
one of two convenient on-board oscillators (66 MHz or 133 MHz) may be
selected instead. Jumper J10 selects the clock source, while jumpers J7 and J8
enable either the 66 MHz or 133 MHz on-board oscillators, respectively.
