HDA576 LVDS OSCILLATORS
7x5mm SMD 6 pad
DESCRIPTION
HDA576 series LVDS output oscillators cover the frequency range
750kHz to 800MHz. The design consists of a crystal operating in 3rd
overtone mode, without a PLL circuit.

Disable:
Both outputs enabled
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.
