FMS6151 Ultra Portable Video Filter Driver Features Description ■ 5th order 8MHz (SD) filter The FMS6151 low cost, integrated, video filter is intended to replace passive LC filters and drivers in low voltage portable video applications. The 5th order filter provides better image quality compared to typical 2nd and 3rd order passive solutions. ■ Power down to 25nA ■ DC-coupled input ■ AC- or DC-coupled output ■ DC coupled output eliminate need for AC-coupling cap ■ SAG correction reduces size of AC-coupling cap The FMS6151 is intended to be directly driven by a DCcoupled DAC output. The output can drive an AC or DCcoupled doubly terminated coax(150Ω) load. DC-coupling the output removes the need for an expensive output coupling capacitor. If an AC-coupled output is needed, the SAG correction circuit can be used to reduce the AC output coupling capacitor value. Input DC levels are offset by approximately 100mV. This internal level shift is incorporated to prevent sync pulse clipping. ■ Fixed gain of 6dB ■ Small, lead-free, Micropak® packaging Applications ■ Digital Still Cameras ■ Camera Phones ■ Personal Digital Assistants ■ Set Top Boxes ■ Digital Video Recorders Offering SAG correction, fixed gain of 6dB, and a 5th order low pass filter in a tiny space saving package (Micropak) makes the FMS6151 well suited for space sensitive applications such as cellular phones and digital cameras.

Shutdown Current vs. Temperature www.fairchildsemi.com 6 FMS6151 — Ultra Portable Video Filter Driver Typical Performance Characteristics SAG Correction Sag correction provides excellent performance with a small output coupling capacitor. It eliminates the 220μF 1000μF output coupling capacitors traditionally used. The traditional output circuit (220μF into 150Ω load) creates a single pole (-3dB) at 5Hz. Reducing this capacitor causes excessive phase shift, resulting in video field tilt which can prevent proper recovery of the synchronization signals. Input Voltage The FMS6151 is intended to be directly driven by a DC coupled DAC output. The input common mode range of the FMS6151 is 1.2Vpp, ground referenced. Enable/Shutdown The FMS6151 has a shutdown feature that disables the output and reduces the quiescent current to ~25nA. This feature is especially useful in portable applications, such as cellular phones, hand held gaming devices, and video cameras requiring video filtering and drive capability. The FMS6151 sag correction circuit provides a small amount of peaking, which provides compensation of the phase response, significantly reducing video field tilt. The SAG correction circuit allows you to decrease the large, 220μF, output coupling capacitor. A 22μF is used for sag correction and a 47μF is used for the output coupling capacitor, extremely smaller and cheaper than the traditional circuit requirements. Internal Level Shift The FMS6151 has an internal level shift circuit to avoid sync tip clipping. The output signal is shifted 200mV toward the VCC rail to help prevent clipping. This offset is extremely useful when DC coupled out or using SAG correction. Output Configuration The FMS6151 output is a low impedance voltage driver. It is capable of driving an AC or DC coupled single load.
