SY02-FEC Preliminary Specification
Date: July 1, 2002
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;
-
Provides free running clock output;
-
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"

DESCRIPTION
The SY02-FEC is a High Frequency Phase Lock Loop has been designed as a module level subsystem for easy
incorporation into telecommunication 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 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 or 5V.
