1. Uses a PLL multiplier, jitter is 25ps rms typical vs 3ps typical for a HFF design
Other frequencies available upon request.
Table 8. Pin Out Information for the PECL output option
Pin Symbol Function
1 VC VCXO Control Voltage
2 N/C or E/D2 No Connect or Output Disable
3 GND Case and Electrical Ground
4 Output VCXO Output
5 COutput VCXO Complementary Output
6 VCC Power Supply Voltage (5.0 V or 3.3 V ±10%)
. By setting OD high, the outputs are disabled and OUT is held low while Complementary OUT is held high. Output is enabled if E/D
< VCC-1.6V,
2. See ordering information for enable/disable option.

1. Power supply bypass is required and a 0.1uF in parallel with a 0.01uF high frequency capacitor is recommended.
2. Transition times are measured from 20% to 80% of a full 10K ECL level swing.
