ADI's reconstruction filter ADA4424-6 integrates an on-chip charge pump and requires only a + 3.3V power supply, providing excellent component video characteristics for today's performance-driven consumer multimedia devices
Beijing, October 23, 2009 / PR Newswire Asia /-Analog Devices, Inc., the world ’s leading provider of high-performance signal processing solutions, has recently introduced a high-performance 6-channel video reconstruction filter (http: / / ADA4424-6), enabling designers of consumer media players and professional video systems (http: //) to easily filter and drive standard definition (SD) and even high definition (HD) video signals. The ADA4424-6 has three standard definition and three enhanced / high definition (ED / HD) channels. The frequency response is extremely flat and there is no peak at the 0.1dB passband, which is what 1080p HD media players and recorders require.
The brightness channel of the ADA4424-6 has 4 unique modes for detecting and eliminating DC input offset voltages up to 1.1V. No DC offset can be achieved at the output pins. ADA4424-6 fully supports the S1 / S2 defined by the EIA CPR-1202 specification and the D-type connector interface defined by the EIAJ CP-4120 standard.
The SD channel of this new filter has a flatness of 6.75 MHz and contains two 5th order Butterworth filters for SD filtering. The SD part also contains a set of built-in Y / C channels for composite video baseband signal output. The ED / HD channel is composed of three 5th-order Butterworth filters with a typical bandwidth of + 0.1dB gain flatness of up to 13.5MHz and 30MHz respectively.
The ADA4424-6 also integrates a charge pump, which allows the output swing to be 1.4V below ground level, thus eliminating the need for large coupling capacitors. The output driver of this filter provides a rail-to-rail output with a fixed gain of 6.2dB. Each output can simultaneously drive two double-ended 75-ohm cables. The filter / buffer part works on a single 3.3V power supply. The device includes a dedicated 5V power pin to support D-type connectors and S1 / S2 signaling.
