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 single-
ended. 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.
Electrical Specifications, T_A = +25° C, Vcc = +3.3V, Vee = 0V, Icc = 85mA
