Functional Diagram
General Description
The HMC865LC3 is a Limiting Amplifier packaged in
a leadless 3x3 mm ceramic surface mount package
which supports up to 43 Gbps operation. The amplifier
provides 30 dB of differential gain. Output voltage
swing is adjustable up to 800 mVp-p differential by
using the VAC analog control input. Additive rms jitter
is less than 300 fs for 32 Gbps operation. HMC865LC3
has an internal DC offset correction circuit which
provides differential 10 mVpp input sensitivity.
All input/output RF signals of the HMC865LC3 are
terminated with 50 Ohms to +3.3V on chip 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.
