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

bandwidth, this amplifier has been optimized for data rates up to 10.7 Gbps and has an input sensitivity (BER < 10-10) 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.

The CX60083, as shown in Figure 7, is available in a 32-terminal flat pack or as shown in Figure 9 in die form. Figure 1 is the system block

diagram.
