TDA9181 Integrated Multistandard Comb Filter

The TDA9181 is a an adaptive PAL NTSC comb Filter with two internal Delay Lines Filters Clock control and input clamps. Video standards PAL B, G, H, D, I, M and N and NTSC M are supported.Two CVBS input signals CAN be selected by means of an input Switch The selected CVBS input signal is filtered to obtain a combed luminance output signal and a combed chrominance output signal. Switched capacitor circuit techniques are used, requiring an internal Clock locked on to the colour subcarrier frequency.The colour subcarrier frequency as well as twice the colour subcarrier frequency may be applied to the IC.In addition to the comb Filter the circuit contains an output Switch so that a selection CAN be made between the combed CVBS signal and an external Y/C signal.The IC is available in a DIP16 and SO16 package. The supply voltage is 5 V.
