Programmable Crystal Oscillator SG-8506CA
Programmable crystal oscillator: SG-8506CA is a low jitter programmable XO at any frequency. Its output frequency is programmable from 50 MHz to 800 MHz with almost 2 ppb resolution.
SG-8506CA consists of XO, PLL and LVPECL output buffer.
XO supplies stable reference clock to PLL with fundamental tone crystal.
PLL consists of a low jitter fractional-N PLL technology. The components for loop filter are embedded into IC, so no external filter component is needed.
● Programmable clock output frequency from 50 MHz to 800 MHz
● Frequency setting resolution is around 2 ppb
● Low jitter and high reliability clock source from the fundamental tone internal crystal
