INTRODUCTION
The SY02-MFTC 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.
-
FEATURES
