Home / Optical receiver module AGC circuit
The TDA520x, TDA521x, TDA522x, TDA7200, TDA7210 and TDA7210V receivers provide an AGC (Automatic Gain Control) circuit that can be used in the active mode or in the inactive low gain mode to extend the dynamic range of the receiver. The circuit diagram of the actual multiplier circuit as illus-trated in Figure 3 makes it easier to determine the multipli-cation constant, M. Automatic Gain Control (AGC) was implemented in first radios for the reason of fading propagation (defined as slow variations in the amplitude of the received signals) which required continuing adjustments in the receiver's gain in order to maintain a relative constant output signal. Download this Guide in PDF format In order to set the AGC control on the module, and specifically for the transmitter module. 2is a schematic of a conventional optical receiver that is suitable for use in the headend facility and in the optical nodes and/or FTTH receivefor receiving optical signals and for providing electrical signals.
