MERCURY
Since 1973
3GPF576 VCXO products feature 0.4 ps typical phase jitter and
low phase noise (-132 dBc at 10 KHz for 155.520 MHz).
Differential PECL Outputs meet the requirements for
SONET, XDSL and other communication protocols.

Function
on pad
No. 2
Both outputs are disabled (high impedance) when pad No. 2 is taken
below 0.45＊Vcc referenced to ground (threshold). Oscillator is always
ON. Only buffer stage is disabled.
Disable
Disable current: 50 uA max. (at 0.0 V).
Disable time: 10 ns max.
At disabled mode, both outputs are enabled when pad No. 2 is taken
above 0.45＊Vcc referenced to ground (threshold).
Enable time: 10ns+one period of the output frequency max.
