HDF5761

Differential LVDS Crystal Clock Oscillators
3HDF5761 Series +3.3V, “F” Family
LVDS Outputs
MERCURY
Since 1973
3HDF5761 products feature 0.4 ps typical phase jitter and
low phase noise (-132 dBc at 10 KHz for 155.520 MHz).
Differential LVDS Outputs meet the requirements for
SONET, XDSL and other communication protocols.
