CNT B • Figure 1 – Block Diagram (***Components outside the dotted line are user supplied) DESCRIPTION The SY02-MFTC 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 200MHz) output from a low jitter VCXO (Crystal Based Oscillator.
The output can be disabled externally by setting OUTEN pin high.
The SY02MFTC can be locked to a user defined input reference signal (from 8KHz to 77.
76MHz…for options please see table ).
