FMS6418

Triple Video Driver with Selectable HD/SD Video Filters for RGB or YUV Signals

Fairchild Semiconductor 

DATA SHEET

FMS6418A

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.
