Dual, VARIABLE GAIN AMPLIFIER

with Low Noise Preamp

FEATURES

DESCRIPTION

The VCA2612 is a highly integrated, dual receive chan-

nel, signal processing subsystem. Each channel of the

● LOW NOISE PREAMP:

• Low Input Noise: 1.25nV/√Hz

• Active Termination Noise Reduction

• Switchable Termination Value

• 80MHz Bandwidth

• 5dB to 25dB Gain

• Differential Input/Output

product consists of a low noise pre-amplifier (LNP) and

a Variable Gain Amplifier (VGA). The LNP circuit

provides the necessary connections to implement Active

Termination (AT), a method of cable termination which

results in up to 4.6dB noise figure improvement. Differ-

ent cable termination characteristics can be accommo-

dated by utilizing the VCA2612’s switchable LNA feed-

back pins. The LNP has the ability to accept both

differential and single ended inputs, and generates a

differential output signal. The LNP provides strappable

gains of 5dB, 17dB, 22dB and 25dB.

● LOW NOISE VARIABLE GAIN AMPLIFIER:

• Low Noise VCA: 3.3nV/√Hz, Differential

Programming Optimizes Noise Figure

• 24dB to 45dB Gain

The output of the LNP can be accessed externally for

further signal processing, or fed directly into the VGA.

The VCA2612’s VGA section consists of two parts, the

Voltage Controlled Attenuator (VCA) and the Program-

mable Gain Amplifier (PGA). The gain and gain range

of the Programmable Gain Amplifier can be digitally

programmed. The combination of these two program-

mable elements results in a variable gain ranging from

0dB up to a maximum gain as defined by the user

through external connections. The output of the VGA

can be used in either a single-ended or differential mode

to drive high performance analog-to-digital converters.

The VCA2612 also features low crosstalk and outstand-

ing distortion performance. The combination of low

noise, and gain range programmability make the

VCA2612 a versatile building block in a number of

applications where noise performance is critical. The

VCA2612 is available in a TQFP-48 package.
