Description
|
The M908-01 is a PLL (Phase Locked Loop) based clock generator that uses an internal VCSO (Voltage Controlled SAW Oscillator) to produce a very low jitter output clock. It is ideal for Gigabit Ethernet. An output clock frequency of 156.25MHz (with the M908-01-156.2500) is provided from eight LVPECL ...
