PLLs Target Networking Equipment

Suitable for use in a wide variety of networking systems, the ZL30100/1 digital PLLs meet Stratum 3 and Stratum 4/4E requirements for access, edge, and customer-premise equipment. The ZL30101 is suited for central office and edge equipment requiring Stratum 3 timing, such as master DSLAMs. Holdover capabilities in the ZL30101 allow externally timed network equipment to receive and send data even when the network synchronization source is lost or interrupted. Both devices accept two references and automatically synchronize to any combination of clocks operating at 8 kHz or 1.544, 2.048, 8.192, or 16.384 MHz. Additionally, they provide a complete range of output clocks including T1/E1 and 4.096, 8.192, 16.384, 32.768, and 65.536 MHz clocks and associated frame pulses with a jitter performance of less than 0.5 ns p-p. Available in 10 mm x 10 mm, 64-pin TQFPs, prices for the ZL30100 and ZL30101 are $10 and $20 each/1,000, respectively. ZARLINK SEMICONDUCTOR, Ottawa, Canada. (613) 592-0200.
