Low Cost Differential Video Receiver Using the ADA4851 Amplifier and the ADV7180 Video Decoder (CN0060)

The circuit described in this document and shown in Figure 1 provides a low cost, low power, unipolar, differential receiver using the ADA4851-1 for an incoming video signal before being digitized by the ADV7180 video decoder. This circuit eliminates common-mode noise and phase noise caused by ground potential difference from an incoming video signal and is well suited for automotive infotainment and vision safety systems.

(Simplified Schematic: Decoupling and All Connections Not Shown)


The ADA4851 family of amplifiers along with the ADV7180 video decoder are all automotive qualified which makes both products ideal for auto-vision applications. Low power, low cost, high speed, and fast settling make these amplifiers well suited for many video applications where these requirements are very important. Figure 1 shows only a single amplifier for simplicity; the amplifier circuit can be repeated for each input as many times as needed.
