Description

Microsemi’s ZL30143 phase locked loop (PLL) is part of the Company’s market-leading
portfolio of single-chip Synchronous Ethernet solutions. The highly integrated products allow
manufacturers to easily upgrade or design networking equipment that supports accurate
end-to-end transmission of voice, video, data and mobile applications and services over
IP-based wired and wireless networks.

Targeting central timing card applications in carrier-grade networking equipment, the
ZL30143 chip integrates analog and digital phase locked loops (APLL/DPLL). The device
provides two independent DPLLs for applications that require independent transmit and
receive timing paths. Delivering high performance at a considerably lower cost versus the
competition, the ZL30143 product requires only an inexpensive temperature controlled
crystal oscillator (TCXO) to achieve full compliance with ITU-T Recommendation G.8262.

Features : 

1. Input reference monitoring for both frequency accuracy and phase irregularities

2. Automatic input reference selection

3. Support of both external timing and line timing modes

4. Hitless reference switching

5. Wander and jitter filtering
