Description

The ZL30414 is an analog phase-locked loop (APLL)

designed to provide jitter attenuation and rate

conversion for SDH (Synchronous Digital Hierarchy)

and

networking equipment. The ZL30414 generates very

low jitter clocks that meet the jitter requirements of

Telcordia GR-253-CORE OC-192, OC-48, OC-12, OC-

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

STM-1 rates.

The ZL30414 accepts a CMOS compatible reference

at 19.44 MHz and generates four LVPECL differential

output clocks at 622.08 MHz, a CML differential

clock at 155.52 MHz and a single-ended CMOS

clock at 19.44 MHz. The output clocks can be

individually enabled or disabled. The ZL30414

provides a LOCK indication.
