Notes

9. The RMS and P-to-P jitter values are measured using a 12 KHz to 20 MHz SONET filter.

10. Typical values are measured at room temperature and the Max values are measured at 0° C.

11. This device passes the Bellcore specification from -10° C to 85° C.

12. The bench jitter measurements are performed using an Agilent Omni bert SONET jitter tester.
