Description
The FMS6366 Filter Driver offers comprehensive filtering for set top box or DVD applications. This part consists of triple 6th order filters with selectable cutoffs for SD or HD. The filters are in a 4:2:2 configuration such that Y1 switches between 8MHz (SD) and 30MHz (HD). The Pb and Pr channels switch between 4MHz (SD) and 15MHz (HD). The required delay compensation must be performed in the digital domain prior to filtering by the FMS6366. An additional S-video path is provided for SD signals. The Y2 and C signals are both filtered at 8MHz. A composite summer is included to provide a composite output based on Y2 and C. A 2:1 multiplexer is provided on each filter channel with separate select lines for the YPbPr and YC signals. All inputs accept DC-coupled ground referenced 1Vpp input signals. The filter outputs include +6dB of gain resulting in a 2Vpp signal into an AC-coupled dual video load (75).

Description
The FMS6366 offers comprehensive filtering for set top box or DVD applications. This part consists of triple 4:2:2 6th order filters with selectable 30/15MHz or 8/4MHz frequencies for YPbPr and a dual 8MHz filter for YC with a composite summer. Two-to-one multiplexers are provided on the triple filters as well as provisions for auxiliary input to the composite channel. The triple filters are intended for YPbPr signals. All channels accept DC coupled ground-referenced 1Vpp signals. The filters output 2Vpp signals into AC coupled terminated loads. The FMS6366 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 4:2:2 HD/SD filtering on the YPbPr channels. Thus, the FMS6366 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 YPbPr and CV channels provide further flexibility. For DVD applications, the product provides filtering and output drive amplification for 6 channels of outputs. These include Y1, Pb, Pr, Y2, C, and CV outputs. For Set top boxes, this product provides two channels of filtered video with 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.

Functional Description
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 at the outputs. The Y channels accept 1Vpp signals with the sync tip at ground. The Pb, Pr and C channels should be centered around 0.5V. This will ensure that the filter will utilize the optimal headroom and avoid clipping.
DC coupling the output of the FMS6366 is allowable, but not recommended. There are several trade-offs: 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. The FMS6366 is specified to operate with output currents typically less than 50mA, more than sufficient for a dual (75) video load. Internal amplifiers are current limited to a maximum of 100mA and should withstand brief duration short circuit conditions, however this capability is not guaranteed.
DC-Coupled Output Applications
The 220uF 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 10uF cause unacceptable tilt in the output signal. By AC coupling, the average DC level is zero. Thus, the output voltages of all channels will be centered around zero.
Driving Digital Pins
The FMS6366 digital inputs are compatible with most 3.3V and 5V logic. Verify that the Vih and Vil are within the specified limits.
Applications
A typical application for the FMS6366 is shown in Figure 1.

Figure 2: Digital Delay Compensation for anti-alias 4:2:2 filters The Chroma filters are one half the bandwidth of the Luminance filter therefore the propagation delay time through the Chroma filter is longer than the Luminance filter. In the Standard Definition (SD) case, the Chroma filter propagation delay is typically 60 nanoseconds longer than the Luminance filter. This is three clock cycles at 54MHz so it is easily corrected by adding digital delay as shown in Figure 3 and illustrated as a shift register in Figure 2. In the High Definition (HD) setting the Chroma filter propagation delay is typically 15 nanoseconds longer than the Luminance filter. This is one clock cycle at 74.25MHz so it is also easily corrected by adding digital delay to the luminance path.
