HDF62 LVDS OSCILLATORS
38.0MHz to 640.0MHz
11.4 x 9.6 x 2.5mm 6 pad SMD
DESCRIPTION
HDF62 series LVDS output oscillators cover the frequency range
38MHz to 640MHz. The design contains a high 'Q' fundamental
crystal and utilizes a low jitter multiplier circuit. Integrated phase jitter
is 0.5ps maximum.

Both outputs enabled
JITTER
(156.520MHz)
Both outputs are disabled when
control pad is taken below 0.3V
referenced to ground. Oscillator is
always 'on'. (Special request -
oscillator is off when disabled.)
Both Outputs are enabled when
control pad is taken above 0.7 Vcc
referenced to ground.
