SYNCHRONOUS EQUIPMENT HIGH FREQUENCY CLOCK REGENERATOR - SY02-FEC Date: January 7, 2003 - INTRODUCTION The SY02-FEC is a high frequency crystal-based PLL synchronizer designed as a module level subsystem for easy incorporation into telemunication equipment SONET/SDH/ATM/DWDM. Supports FEC (forward error Correction) or OC-N Frequencies. - - Features Low jitter output from intrinsically low jitter VCXO or VCSO; User Selected one or two input references up to 800MHz ( See Table on page 3) One high frequency LVPECL output with enable/disable function up to 800MHz (pre-select frequency value - upon order) Alarms status and VCXO monitor; The unit changes timing modes in response to external events; J-TAG service port for re-programming and servicing; 3.3V DC power supply Small dimensions: 0.8” x 1.00” - - APPLICATIONS ATM SDH PDH SONET DWDM FEC Other telemunication equipment.

The module generates the high frequency (up to 800MHz) output from a low jitter VCXO (Crystal Based Oscillator) or VCSO (SAW based oscillators). The output can be disabled externally by setting OUTEN pin high. The SY02-FEC can be locked to a user defined input reference/s signal/s (from 1.024MHz to 800MHz…for options please see table ). Raltron’s SY02-FEC device could be used as a frequency translator in PLL circuits or...
