Integrated Circuit Systems, Inc. Communications Modules www.icst.com/Comm-Modules tel: 508-852-5400 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.
