Century Semiconductor Inc. CS6723 CS6723 2.5Gbps Fiber-Optic Quantizer FEATURES The CS6723 CS6723 postamplifier is a high gain, wide bandwidth limiting amplifier for use in fiber-optic based communications up to 2.5Gbps. Inputs of the CS6723 CS6723 are differential and AC-coupled from the transimpedance amplifier. Further, the inputs are self-biased by internal circuits and the input offset compensation is accomplished by using an external capacitor between the CAZP and CAZN pins. The CS6723 CS6723 includes a user programmable signal strength detector, enabling the user to set voltage thresholds at which the logic outputs are enabled. The link detection output pins (LINKP/LINKN) are available in both CMOS (CS6723C CS6723C) and PECL (CS6723E CS6723E) output interfaces. Data output of the CS6702 CS6702 is differential PECL. The output buffer can be gated using the JAM pin. · Fully differential architecture. Input Sensitivity spans 2mV to 500mV. · Minimum 2.5GHz bandwidth with Maximum gain of 50dB. · Programmable input-signal level detection. · CMOS or PECL link status output. · Pin-compatible with Microcosm MC2046-2 MC2046-2. · Supports 3.3 Volt operation. · Available as die or in a QFN package. · CML or PECL data output.
