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.

CONTROL VOLTAGE VAC (V)
In order to adjust the DC voltage on VAC pin a resistor, Rc, should be connected between VAC pin and VCC as shown
in the figure below.
The value of the resistor can be chosen using the following equation as a function of VAC. VAC DC voltage value can
be chosen by using the plot given above.
