General Description

The CLC520 is a wideband DC-coupled amplifier with voltage controlled gain (AGC). The amplifier has a high impedance, differential signal input; a high bandwidth, gain control input; and a single-ended voltage output. Signal channel performance is outstanding with 160MHz small signal bandwidth, 0.5 degree linear phase deviation (to 60MHz) and 0.04% signal nonlinearity at 4V_PP output.

Gain control is very flexible and easy to use. Maximum gain may be set over a nominal range of 2 to 100 with one external resistor. In addition, the gain control input provides more than 40dB of voltage controlled gain adjustment from the maximum gain setting. For example, a CLC520 may be set for a maximum gain of 2 (or 6dB) for a voltage controlled gain range from 40dB to less than 34dB. Alternatively, the CLC520 could be set for a maximum gain of 100 or (40dB) for a voltage controlled gain range from 40dB to less than 0dB.

The gain control bandwidth of 100MHz is superb for AGC/ALC loop stabilization. And since the gain is minimum with a zero volt input and maximum with a +2 volt input, driving the control input is easy.

Finally, the CLC520 differential inputs, and ground referenced voltage output take the trouble out of designing DC-coupled AGC circuits for display normalizers; signal leveling automatic circuits; etc.
