CMOS Output Option
3
Output Test Conditions (25±5°C) for 5 volt devices.
For 3.3V use 15pF cap only, no resistors needed.
Threshold = 1.4 volts for TTL
and 50% for CMOS

1. Output is CMOS and symmetry is tested at TTL and CMOS thresholds.
2. Output is CMOS and symmetry is tested at CMOS threshold. This option is used for 3.3 V operation.
3. Output is CMOS and symmetry is tested at CMOS thresholds. This option is required for 3.3V, frequencies >51.840MHz.
4. Note: Not all combinations are possible.
Example: JDUGCKTN @ 77.76 MHz = 3.3 volt, VCXO@77.760, ±50 ppm APR, 0/70°C, 40/60% Symmetry,
CMOS, Tri-State on pin 2.
1. Uses a PLL multiplier, jitter is 25ps rms typical vs 3ps rms typical for a HFF (High Frequency Fundemental) design. Available with 5 Vdc input only.
Other frequencies available upon request.
