Crystal Oscillators (XO’s)
XO-400
Description:
Vectron International has introduced a series of low
cost complementary PECL Crystal Oscillators (XO’s)
available in frequencies from 15 MHz to 250 MHz in a
standard 4 pin DIP package. This series offers ultra low
jitter of <0.5 ps rms from 12 kHz to 20 MHz bandwidth.
Features:
• Ultra low jitter
• 3.3 Vdc or 5 Vdc operation
• Complementary PECL output
• Standard 4 pin DIP package
