5. Brief Description and Characteristics
The Word Clock Module WCM is a small companion board to RME's DIGI96 series, and
needs no slot on the motherboard. It adds a word clock input and output to these powerful digi-
tal interface cards. Both connectors are BNC jacks, so there's no hassle with adapters. The
module includes an optimized low jitter PLL for reliable reconstruction of the audio clock signal,
a low impedance output, and a complete word clock generator, usable as master clock or for
test and check purposes.
The WCM is connected to the DIGIs using two supplied cables. After connection it is imme-
diately ready to operate. The drivers of the DIGI96 series are already prepared for an opera-
tion with the WCM.
Thanks to several LEDs (power, test mode, LOCK) and the highly integrated concept of instal-
lation, first operation and usage are simple even for the unexperienced user.
