GENERAL DESCRIPTION
The CTM 5100R is manufactured in Champion's ISO 9001 Certified facility located in Franklin
Park, Illinois. The CTM5100R is a Stratum III Timing Module that can lock to one of two 8KHz
reference input frequencies.
Further features include alarms for Loss-Of-Reference (LOR), or Loss-Of-Lock (LOL) condi-
tions. Upon LOR the CTM5100R can be entered into a holdover state that will maintain a
<±0.37 ppm frequency stability over 24 hours. A tuning limit alarm is also available for notifica-
tion of possible reference problems.
The CTM5100R is available in a 2"x2" 18 pin package. Power consumption is typically less
than 750mW at 25oC.
Champion's Engineering Staff can also modify or customize the CTM5100R for your applica-
tions for optional output frequencies and bandwidth requirements.
