ZL30416

SONET/SDH Clock Multiplier PLL

Data Sheet

November 2004

Features

•

Low jitter clock outputs suitable for OC-192, OC-

48, OC-12, OC-3 and OC-1 SONET applications

as defined in Telcordia GR-253-CORE

Ordering Information

ZL30416GGG

64 Ball CABGA

Low jitter clock outputs suitable for STM-64, STM-

16, STM-4 and STM-1 applications as defined in

ITU-T G.813

-40°C to +85°C

Provides one differential LVPECL output clock

selectable to 19.44, 38.88, 77.76, 155.52 or

622.08 MHz

Description

The ZL30416 is an Analog Phase-Locked Loop (APLL)

designed to provide jitter attenuation and rate

conversion for SDH (Synchronous Digital Hierarchy)

and SONET (Synchronous Optical Network)

networking equipment. The ZL30416 generates low

jitter output clocks suitable for Telcordia GR-253-

CORE OC-192, OC-48, OC-12, OC-3, and OC-1 and

ITU-T G.813 STM-64, STM-16, STM-4 and STM-1

applications.

•

Provides a single-ended CMOS output clock at

19.44 MHz

Accepts a single-ended CMOS reference at

19.44 MHz or a differential LVDS, LVPECL or

CML reference at 19.44 or 77.76 MHz

•

Provides a LOCK indication

8 mm x 8 mm CABGA package

3.3 V supply

The ZL30416 accepts a CMOS compatible reference

at 19.44 MHz or a differential LVDS, LVPECL or CML

reference at 19.44 or 77.76 MHz and generates a

differential LVPECL output clock selectable to 19.44,

38.88, 77.76, 155.52 or 622.08 MHz and a single-

ended CMOS clock at 19.44 MHz. The ZL30416

provides a lock indication.
