M840 Series
Performance Specifications
The M840 Series OC-192 Multi-rate Clock
Recovery Module provides low jitter clock recovery
from NRZ or RZ input data formats. Four data
rates, 9.953, 10.3125, 10.664 or 10.709Gb/s may
be selected digitally. The input data is amplified by
limiting amplifiers. The amplified data is applied to
the clock recovery circuitry and provided as an
output at a constant level.
The module incorporates a frequency multiplied
high Q SAW VCO in the clock recovery phase-lock
loop to minimize the jitter on the recovered clock.
The low noise, excellent stability, and low micro-
phonic sensitivity of the SAW based VCO to allow
operation with a very narrow phase-lock loop
bandwidth necessary to minimize pattern
dependent clock jitter. The use of micro-strip band
pass filters to filter the recovered clock results in a
sinusoidal clock output, having low harmonic and
sub-harmonic distortion.
The clock recovery circuitry is housed in an easy to
interface connectorized module. The discrete
circuit design allows for the design to be optimized
for various applications and data rates.
