Data Sheet

2.0 Applications

2.1 Ultra-Low Jitter SONET/SDH Equipment Clocks

The ZL30406 functionality and performance complements the entire family of the Zarlink’s advanced network

synchronization PLLs. Its superior jitter filtering characteristics exceed requirements of SONET/SDH optical

interfaces operating at OC-48/STM-16 rate (2.5 Gbit/s). The ZL30406 in combination with the MT90401 or the

ZL30407 (SONET/SDH Network Element PLLs) provides the core building blocks for high quality equipment clocks

suitable for network synchronization (see Figure 4).
