Differential LVPECL Crystal Clock Oscillators
HPK5761 Series 200 fsec Jitter +2.5V +3.3V “K” Family
MERCURY
Since 1973
Femto second integrated phase jitter (200 fs typical, 12 KHz to 20 MHz)
Superior phase noise (-138 dBc/Hz at 10 KHz and -144 dBc/Hz at 100 KHz offset).
High performance with surprisingly low price.
2.5V or 3.3V supply voltage.
