SCG4000 V3.0 Series Synchronous Clock Generators PLL 2111 Comprehensive Drive Aurora, Illinois 60505 Phone: 630- 851- 4722 Fax: 630- 851- 5040 www.conwin.com Application The Connor-Winfield SCG4000 Series provides high precision phase lock loop frequency translation for the telecommunication applications. SCG4000 Series is well suited for use in line cards, service termination cards and similar functions to provide reliable reference, phase locked, synchronization for TDM, PDH, SONET and SDH network equipment. The SCG4000 Series provides a jitter filtered, wander following output signal sychronized to a superior Stratum or peer input reference signal. Features 3.3V High Precision PLL Tri-State Capability Active Alarms Guaranteed Free Run ±20ppm 1 sec. Acquisition Time www.DataSheet4U.com Bulletin Page Revision Date Issued By SG031 1 of 12 01 30 JULY 02 MBatts General Description The SCG4000 Series is a digital phase locked loop generating a LVPECL outputs from an intrinsically low jitter voltage controlled crystal oscillator. The LVPECL outputs may be disabled. The jitter attenuated internal reference, divided down from the output frequency, is also output to a pin. The SCG4000 Series can lock to one of four possible reference frequencies from 8 to 64 kHz, which is selectable using two input select pins. A filtered reference output signal is available at the same frequency. The unit has an acquisition time of about 1 second and it is tolerant of different refe...
