Programmable output synthesizers (P0, P1)

generate telecom clock frequencies from any

multiple of 8 kHz up to 100 MHz

Generates standard SONET/SDH clock rates

(e.g., 19.44 MHz, 38.88 MHz, 77.76 MHz,

155.52 MHz, 622.08 MHz) or Ethernet clock rates

(e.g., 25 MHz, 50 MHz, 125 MHz, 156.25 MHz,

312.5 MHz) for synchronizing Gigabit Ethernet

PHYs

Client reference switching between multiple

Servers

Client holdover when Server packet connectivity is

lost
