Functional Diagram
General Description
The HMC866LC3C is a Limiting Amplifier packaged in a leadless 3x3 mm ceramic surface mount package. The amplifier supports up to 43 Gbps operation and provides 29 dB of differential gain. The output voltage swing is adjustable up to 800 mVp-p differential by using the VAC analog control input and the additive RMS jitter is less than 300 fs for 32 Gbps operation. The amplifier allows external offset correction function to both inputs and outputs. All input/output RF signals of the HMC866LC3C are terminated with 50 Ohms to +3.3V internally and may be either AC or DC coupled. The outputs of the device can be operated either differentially or singleended. Outputs can be connected directly to 50 Ohm terminated system referenced to 3.3V, while DC blocking capacitors may be used if the terminating system is 50 Ohms to a non 3.3V level.

The circuit board used in the application should use RF circuit design techniques. Signal lines should have 50 Ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
