Data Sheet CX60083-15/-2A 10 Gbps High Gain Limiting Amplifier Key Features Limiting amplifier Integrated LOS and peak detect circuit Wide bandwidth and high sensitivity Compatible with DC- or AC-coupled input and output signals Fully differential architecture Optional single-ended input and/or output operation Available in a 32-terminal, 5 mm square EdQuad TQFP or as dice Applications Fiber-optic communications (OC-48/OC-192) SONET/SDH test equipment Data communications Product Description The CX60083 is a high-gain, wide-bandwidth, limiting amplifier ideal for use as a post-amplifier in fiber-optic receivers. With its 10GHz -10 bandwidth, this amplifier has been optimized for data rates up to 10.7 Gbps and has an input sensitivity (BER < 10 ) of 5 mV, differential. It accepts both single-ended and differential inputs and may be either AC- or DC- coupled. With approximately 39 dB of small signal gain, this amplifier can limit input voltages at or above 5 mV P-P (single-ended) to an output voltage of 460 mV P-P (single-ended). An on-chip Loss of Signal (LOS) detection circuit with hysteresis provides an LOS output signal. A high-gain, on-chip, peak detector provides a DC output signal that is linearly proportional to the input signal amplitude. This signal can be used for Automatic Gain Control (AGC) of preceding amplifier stages or a custom LOS network. High-impedance differential outputs and inputs are available for input voltage offset correction. T...
