Description

The FMS6151L6X is a Linear - Video Processing electronic component designed for comprehensive video filtering for set-top box or DVD applications. This chip integrates a video driver, and an integrated clamp circuit for DC restoration. The video output is filtered at 7.1MHz, and it approximates a 4th-order Butterworth characteristic with an optimization toward low overshoot and flat group delay. It can deliver 2Vp-p composite video into a 150Ω AC coupled load with up to 35pF of load capacitance at the output pin.

Specifications and features

• Integrated Video Low Pass reconstruction filter
• Integrated output driver provides a low impedance output and delivers 2Vp-p (6dB gain) composite video into 150Ω.
• 7.1MHz 4th order video filter
• 0.4% differential gain with 0.4° differential phase
• Integrated DC Restore / Clamp Circuitry

Application Scenarios

This chip is widely used in various applications such as:

• CCTV
