(400 Ω Differential or 100 Ω Differential) 1 Functional Diagram General Description
The HMC960LP4E is a digitally programmable dual
channel variable gain amplifier. It supports discrete
gain steps from 0 to 40 dB in precise 0.5 dB steps.
It features a glitch free architecture to provide
exceptionally smooth gain transitions. The device
has matched gain paths which provide excellent
quadrature balance over a wide signal bandwidth.
The HMC960LP4E provides an SPI programmable
input impedance of 100 Ω differential or 400 Ω
differential (default).
Externally controlled common mode output feature
enables the HMC960LP4E to provide a flexible output
interface to other parts in the signal path.
Gain can be controlled via either a parallel interface
(GC[6:0]) or via the read/write serial port (SPI). …
