TMA

SYNCHRONOUS TIMING MODULES TMA SERIES SYNCHRONOUS TIMING MODULES 8kHz to 77.760MHz Inputs, up to 77.760MHz CMOS output DESCRIPTION TMA (Synchronous Timing Module, model A) parts serve as a frequency translator in telecommunications systems. The device translates any CMOS input reference frequencies (8, 16, 32, 64kHz up to 77.760MHz) into jitter-attenuated, phase locked reference synchronized output frequencies up to 77.760MHz. Page 1 of 2 OUTLINES & DIMENSIONS FEATURES Loss of Reference (LOR) and Loss of Lock (LOL) active alarms. Continuous input reference monitoring of external references. Automatic FREE RUN mode on Loss Of Reference (LOR) ±15ppm output accuracy guaranteed. Manually forced FREE-RUN mode by software control. Tristate (output high impedance) for external testing. +3.3V leadframe package, current
