GENERAL DESCRIPTION
The CTM 5002A is manufactured in Champion's ISO 9001 Certified facility located in
Franklin Park, Illinois. The CTM 5002A is a Frequency Translator that will lock to an
input of 77.760MHz, providing a very low jitter output at 77.760MHz (9ps RMS). A vari-
ety of input/output frequencies for T1, E1, OC-n and STM applications are also avail-
able.
Further features include alarms for Loss-Of-Reference (LOR), or Loss-Of-Lock (LOL)
conditions. Upon LOR the CTM 5002A will automatically enter a "free run" state that
will maintain a
±
20ppm frequency stability. A Tri-State enable/disable function is also
available for testing purposes.
The CTM 5002A is available in a Surface Mount Package that is leaded to be compati-
ble with a variety of SMD manufacturing processes.
CTM5002A is a member of Champion’s CTM5000 Series of Frequency Transalator
Modules. Our experienced engineering Staff can also offer custom modules for specific
applications.
