电荷泵6通道SD / ED / HD视频滤波器 6-Channel SD/ED/HD Video Filter with Charge Pump
Product Details
The ADA4424-6 is a high performance video reconstruction filter specifically designed for consumer applications. It consists of a standard definition SD section with two fifth-order Butterworth filters, and a high definition HD section with three fifth-order filters. The SD section contains an internal Y/C summer for CVBS output, whereas the HD section provides selectable corner frequencies for either extended definition ED or HD signals.
The ADA4424-6 filter/buffer section operates from a single 3.3 V supply. Full support for D-terminal EIAJ RC-5237 D5 and S1/S2 signaling is provided, along with a dedicated 5 V supply pin. Separate enable pins are provided for the SD and HD sections.
The luma channels Y_IN, HY_IN of the ADA4424-6 are capable of detecting and cancelling dc input offsets of up to 1.1 V. Four distinct modes of detection/cancellation are available.
The output drivers on the ADA4424-6 feature rail-to-rail outputs with 6.2 dB gain. An on-board charge pump allows the outputs to swing up to 1.4 V below ground, eliminating the need for large coupling capacitors. Each output is capable of driving two 75 Ω doubly terminated cables.
The ADA4424-6 is available in a 38-lead TSSOP and operates in the extended industrial temperature range of −40°C to +85°C.
