General Description
The FMS6419 offers comprehensive filtering for set top box or DVD applications. This part consists of triple 6th order filters with selectable 30MHz or 8MHz frequencies and a dual filter for filtering Y, C with a composite summer. 2 to 1 multiplexers are provided on the triple filters as well as provisions for auxiliary input to the composite channel. The triple filters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1V signals. The filters outputs 2Vpp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and output buffers are powered by 5.0V. The FMS6419 is a next generation filter solution from Fairchild Semiconductor addressing the expanding filtering needs for set top boxes, and DVD players. The product provides selectable filtering from 30MHz to 8MHz on the RGB channels. Thus, the FMS6419 addresses the requirement for a single set top box to be compatible with a variety of resolution standards. Additionally, the product provides additional filters for Y, C, and Composite Video (CV) outputs. Multiplexers on the RGB and CV channels provide further flexibility. For DVD applications, the product provides filtering and output drive amplification for 6 channels of outputs. These include R, G, B, Y, C, and CV outputs. For Set top boxes, this product provides for 2 channels of video to be filtered, as well as the flexibility of selectable high order filtering for multiple resolution standards. Additional flexibility is provided by the Y (Luma) and C (Chroma) filters with a composite summer. All channels provide 6dB gain, accept 1V ground referenced inputs, and drive AC coupled loads. The filters for the R, G, B, Y, C, and CV channels are powered from a 3.3V supply and the outputs from 5V.

Applications
DC Levels
At any given time, the input signal's DC levels must be between 0.0V and 1.3V to utilize the optimal headroom and to avoid clipping on the outputs. The Y channel should nominally have the Sync Tip at ground and be a 1V signal. The C channel should ride around the 0.5V level. This will ensure that the filter will utilize the optimal headroom and avoid clipping.
0F would create a problem. By AC coupling, the average DC level is zero. Thus, the output voltages of all channels will be centered around zero. Alternately, DC coupling the output of the FMS6419 is allowable, but not recommended. There are several tradeoffs: The average DC level on the outputs will be 2V. Each output will dissipate an additional 40mW nominally. The application will need to accommodate a 1V DC offset sync tip. Also, it is recommended to limit one 150 load per output.
DC Coupled Output Applications
The 220F capacitor coupled with the 150 termination forms a high pass filter that blocks the DC while passing the video frequencies and avoiding tilt. Lower values such as
Driving the Digital Pins with 3.3V or 5V Logic
Either is allowed as long as the Vih and Vil are adhered to.
