IC offers single chip synchronous clock solution for SETS.

Press Release Summary:




Fully compliant with ITU-G.813 and Telcordia GR1244 and GR253, Model STC5230 offers single chip solution for timing source in SDH, SONET, and Synchronous Ethernet network elements. It accepts 12 reference inputs and generates 9 independent synchronized output clocks, and offers 2 independent timing generators, T0 and T4, for Synchronous Equipment Timing Source (SETS). Available in TQ100 package, device operates with external OCXO or TCXO as its MCLK at 20 MHz.



Original Press Release:



Connor-Winfield's New STC5230 Is a Single Chip Synchronous Clock Solution for SETS



August, 2008

Aurora, IL - The STC5230 is a single chip solution of timing source in SDH, SONET, and Synchronous Ethernet network elements. The device is fully compliant with ITU-G.813 and Telcordia GR1244 and GR253.

The STC5230 accepts 12 reference inputs and generates 9 independent synchronized output clocks. Reference input frequencies are automatically detected, and inputs are individually monitored for quality. Active reference selection may be manual or automatic. All reference switches are hitless. Synchronized outputs may be programmed for a wide variety of SONET and SDH as well as Synchronous Ethernet frequencies.

Two independent timing generators, T0 and T4, provide the essential functions for Synchronous Equipment Timing Source (SETS). Each timing generator includes a DPLL (Digital Phase-Locked Loop), which may operate in the Freerun, Synchronized, and Holdover modes. Both timing generators support master/slave operation for redundant applications. The proprietary SyncLink(TM) cross-couple data link provides master/slave phase information and state data to ensure seamless side switches.

A standard SPI serial bus interface provides access to the STC5230's comprehensive, yet simple to use internal control and status registers. The device operates with an external OCXO or TCXO as its MCLK at 20 MHz.

The STC5230 is capable of field upgrade with optional external EEPROM or via the bus interface.
