www.fairchildsemi.com ML6415 DEMO Demonstration board for the ML6415 Features Description * * * * * * * * The ML6415 DEMO demonstration board provides a flexible base for evaluating the performance of the ML6415. The ML6415 is a dual Y/C 4th-order Butterworth lowpass video filter optimized for minimum overshoot and flat group delay. The device also contains a summing circuit to generate filtered composite video, an audio trap and group delay compensation circuit to notch-out audio, providing an area for the addition of the FM audio carrier(s) and mimic the group delay distortion introduced at the transmitter. For a complete description of the ML6415 including typical applications, please refer to the ML6415 data sheet. The ML6415 DEMO also has an option to connect YIN, CIN, YOUT, COUT, CVOUT, or RFOUT to 75 Ohm terminated to Ground (Jumpers labeled as JP1-6). 7.1MHz Y and C filters, with CV out 14dB notch at 4.5 MHz for sound trap 42dB stopband attenuation at 27 MHz on Y, C, and CV Better than 1dB flatness to 4.5MHz on Y, C, and CV Capable of driving 75 Ohm cable AC coupled inputs and outputs No external frequency select components or clocks 5% overshoot on Y, C, and CV output edges Applications * Cable Set-top Boxes * Satellite Set-top Boxes * DVD Players Block Diagram N/C GND +5V RFMOD YIN GND YOUT VCC RFMOD YIN ML6415 CIN CIN 8-Pin SOIC YOUT CVOUT CVOUT COUT COUT PRELIMINARY INFORMATION describes products that are not in full production at the time of printing.
