ACS8944数据手册集成电路（IC）的应用特定时钟/定时规格书PDF

特性 Features

·Meets rms jitter requirements of: ·Telcordia GR-253-CORE for OC-3 and OC-12
·ITU-T G.813/G.812 for STM-1 and STM-4 rates
·ETSI EN300-462-7/EN302-084 up to STM-16 rates

·Typical jitter generation down to: ·0.3 ps rms for 250 kHz to 5 MHz band for G.813, or EN300-462, at STM-4 (OC-12) rates
·2.8 ps rms for 12 kHz to 20 MHz band (against 4.02 ps rms for GR-253-CORE at OC-48 rate)

·Pull-in range ±400 ppm about center input frequency
·Frequency translation e.g. 19.44 MHz to 155.52 MHz
·3.3 V operation, - 40 to +85°C temperature range
·Small outline leadless 7 mm x 7 mm QFN48 package
·Demonstration Board available on request
·PLL bandwidth and jitter peaking are fully adjustable.
·Supports bandwidths from 2 kHz for superior input jitter filtering
·Lead (Pb)-free version available (ACS8944T), RoHS and WEEE compliant
