SY02-FEC

SYNCHRONOUS EQUIPMENT HIGH FREQUENCY CLOCK REGENERATOR - SY02-FEC 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 telecommunication 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 telecommunication equipment.
