Synch Module suits Stratum 3 applications
Press Release Summary:
Suited for synchronous timing source in SONET/SDH network elements, Model STC3500 integrated single-chip solution operates in free-run, locked, and hold-over modes. It supports master/slave operation, includes continuous input reference quality monitoring, and accepts 8 auto frequency detect reference inputs from 8 kHz to 77.76 MHz and one 8 kHz cross-reference. Module provides 4 output signals and configurable bandwidth filter from .08-1.4 Hz.
Original Press Release:
Connor Winfield's STC3500 - A Single Chip Solution for a New Generation of Stratum 3 Synch Applications
As the pioneer in synchronization modules, Connor Winfield recently introduced their latest generation of synch modules - the SM3, which is the smallest synch module in the industry. Now, Connor-Winfield has taken this one step further and is offering design engineers the option of purchasing the STC3500 as a stand-alone chip.
The STC3500 is an integrated single chip solution for the synchronous timing source in SONET/SDH network elements. It is the same engine as in the SM3 module and is fully compliant with Telcordia GR-1244-CORE, GR-253, ITU-T G.812 Type IV and ITU-T-G813 Option 1 when used with applicable oscillator.
The STC3500 can operate in Free Run, locked or Hold Over mode, and supports Master/Slave operation with continuous input reference quality monitoring.
Features of the new STC3500 include:
o Great flexibility for Design Engineers
o Complies with Telcordia GR-1244-CORE, GR-253, and ITU-T G.812/G.813
o Supports Master/Slave operation
o Supports Free Run, Locked, and Hold Over modes
o Accepts 8 auto frequency detect reference inputs from 8 kHz to 77.76 MHz and one 8 kHz cross reference
o Continuous input reference quality monitoring
o Input reference frequency can be manually selected or automatically detected
o Four output signals: one selectable up to 77.76 MHz, one fixed at 8 kHz, one multi-frame sync fixed at 2 kHz, and 1.544 MHz or 2.048 MHz VBITS output
o Output phase is adjustable in slave mode
o Frequency ramp control during reference switching
o Hit-less reference switching
o Phase build-out on reference switching
o .05ppm hold over accuracy
o Configurable bandwidth filter .08 to 1.4 Hz
o Supports SPI and 8-bit parallel bus interface
o IEEE 1149.1 JTAG boundary scan
o Available in FBGA144 package
Prototype quantities are available now. Production quantities priced at $98 @ 1000 pieces with 4-6 Weeks Lead-Time.
