• INTRODUCTION
The SY05-HF is a high frequency clock that has been designed to be use
at high speed Line Interface Cards in telecommunication products mainly
related to STN-n or OC-n.
• FEATURES
√ A high frequency clock intended to be used at line cards for OC3 and OC12 (STM3 and STM12).
√ Along with SY0001 or SY0010 provides complete timing solution.
√ Provides very low jitter output signal.
√ Performs hitless switching between two reference signals.
√ Supports four timing modes: (1) Free-run, (2) Locked to Reference 1 (3) Locked to Reference 2, and (4) Loop back
timing.
√ Accepts reference inputs from two clock sources – 8KHz~77.76MHz
√ Provides up to 4 LVPECL outputs and two LVCMOS outputs up to 777.6 MHz. (or alternatively 5 LVPECL outputs)
√ Manual or Automatic selection between operating modes.
√ Alarm and status signals.
√ Complies with ITU-T Recommendations G.813, ETSI-ETS 300 462-4 and Bellcore GR-1244-CORE for Stratum 3 and
3E applications.
√ Small dimensions of 1.80 x 1.80 x 0.429 inch. (Without Metal Cover)
• APPLICATION
The SY05-HF high frequency clock can be used in ATM, SDH, PDH, and SONET networks devices. It is designed for
manufacturers of network equipment, especially Access Switches, Core Switches, Cross Connects, Digital Multiplexers-
Exchangers, and SDH/SONET equipment. The SY05-HF is a timing solution for Line Interface Cards.
