General Description
The CLC522 variable gain amplifier (VGA) is a dc-coupled, two-quadrant multipliers with differential voltage inputs and a single-ended voltage output. Two input buffers and an output operational amplifier are integrated with the multiplier core and make the CLC522 a complete VGA system that does not require external buffering.
The CLC522 provides the flexibility of externally setting the maximum gain with only two external resistors. Greater than 40dB gain control is easily achieved through a single high impedance voltage input. The CLC522 provides a linear (in Volts per Volt) relationship between the amplifier's gain and the gain-control input voltage.
The CLC522's maximum gain may be set anywhere over a nominal range of 2V/V to 100V/V. The gain control input then provides attenuation from the maximum setting. For example, set for a maximum gain of 100V/V, the CLC522 will provide a 100V/V to 1V/V gain control range by sweeping the gain control input voltage from +1 to -0.98V.
Set at a maximum gain of 10V/V, the CLC522 provides a 165MHz signal channel bandwidth and a 165MHz gain control bandwidth. Gain nonlinearity over a 40dB gain range is 0.5% and gain accuracy at AVmax = 10V/V is typically ±0.3%.
