•
INTRODUCTION
The SY02-MFTP 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 multiplexing of up to 4
independent references translated into one single jitter free
frequency source.

DESCRIPTION
The SY02-MFTP 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 170MHz) output from a
low jitter VCXO (Crystal Based Oscillator. The output can be disabled externally by setting OUTEN pin high. The SY02-
MFTP can be locked to a user defined input reference signal
(from 8KHz to 77.76MHz…for options please see table ).
Frequency selection could be simultaneously achieved of up to 4 independent sources while combining the module with an
external MUX. Raltron’s SY02-MFTP 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-MFTP 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.
