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

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.
