Clock

A stable, external 25MHz reference clock source (TTL) is required to the CLK25 pin. The

reference clock is used to generate transmit signals and recover receive signals. A crystal-based

clock is recommended over a derived clock (i.e., PLL-based) to minimize transmit jitter. Refer to

Table 18 for a list of recommended oscillators and to Table 21 on page 44 for clock timing

requirements.
