Description
The FMS6418A offers comprehensive filtering for set top box or DVD applications. This part consists of a triple 6th order filter with selectable 30MHz or 8.0MHz frequencies. A 2-to-1 multiplexer is provided on each filter channel. The triple filters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1V signals. The filters provide 2Vpp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and the outputs by 5.0V. The FMS6418A is available in both 16-pin SOIC and 14-pin TSSOP packages.
Applications
* Cable Set top boxes * Satellite Set top boxes * DVD players * HDTV * Personal Video Recorders (PVR) * Video On Demand (VOD)

General Description
The FMS6418A offers comprehensive filtering for set top box or DVD applications. This part consists of a triple 6th order filter with selectable 30MHz to 8.0MHz frequencies. A 2-to-1 multiplexer is provided on each filter. The filters are intended for either YUV or RGB signals. All channels accept DC coupled ground-referenced 1V signals. The filters provide 2Vpp signals into AC coupled terminated loads. All channels provide 6dB gain, accept 1V ground referenced inputs, and drive AC coupled loads. The RGB low-pass filters are powered by 3.3V and the output buffers are powered by 5.0V. The FMS6418A 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 with cutoff frequencies of 30MHz or 8.0MHz on the RGB/YUV channels. Thus, the FMS6418A addresses the requirement for a single set top box to be compatible with a variety of resolution standards. Multiplexers on the RGB channels provide further flexibility. For DVD, Set-top Box, and TV applications, the product provides filtering and output drive amplification for three channels of outputs (RGB/YUV).

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.
Single Supply +5V Operation
For low power consumption, the FMS6418 was designed to operate off of 5V and 3.3V. VCCA can be operated from 5V instead of 3.3V and still meet specifications, except power consumption. When the 3.3V supply is increased to 5V, the typical current consumption increases by 5mA. The net effect is the part dissipates an additional 22 percent of power.
Driving the Digital Pins with 3.3V or 5V Logic.
Either is allowed as long as the Vih and Vil are adhered to.
