SYNCHRONOUS EQUIPMENT HIGH FREQUENCY CLOCK REGENERATOR - SY02-FEC Date: January 7, 2003 SY02-FEC * 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. th RALTRON ELECTRONICS CORP. 10651 N.W.19 St Florida 33172 U.S.A.

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 frequency re-generator device in cases where jitter cleaning and filtering is required. The module has a fast locking time and tolerates reference inputs with different duty cycles. The loop bandwidth is optimized in accordance with the VCXO used and required output performance. The ALARM output signals monitor the status of the phase lock loop and indicates LOLD (Loss of Lock Detect). If the reference REF IN is absent, the SY02-FEC will automatically switch to free run mode and LOLD will show "0" logic level. The SMD package dimensions are 0.80"x1.00" inch and powered by a supply of 3.3V.
