CRYSTAL CONTROLLED OSCILLATORS

The Connor-Winfield

FPLA521 is a fixed frequency,

surface mount Crystal

Controlled Oscillator (XO)

designed for applications

requiring low jitter and a

±50ppm overall stability.

Operating at 3.3V supply

voltage, the FPLA521

provides LVPECL

complementary outputs.
