Absolute Pull Range (ppm) ±100min. Output Tristate Control Pin #5,

Frequency 77.76MHz.

Notes:

Pin Out

1. Current is frequency and load dependent.

2. Tighter duty cycle available.

3. ±100ppm available at some frequencies. ±32ppm for some

frequencies at 3.3V is the only option.

4. 0–5V control voltage available for Vcc 3.3V. Nominal control

voltage is 2.5V and setability is ±0.5V in this case.

5. For higher frequency Tr/ Tf is shorter.

Leak rate less than 5 x 10^–8atm.cc/ s of helium
