Press Release Summary:
FMS6413 single-channel filter/driver features 1.0 dB flatness across pass band, 7.1 MHz cutoff frequency, and 37 dB stop-band rejection at 27 MHz. Filter approximates performance of 4th order Butterworth filter, and driver can drive 2Vp-p into 150 ohm load. Monolithic device includes DC restore/sync-tip clamp circuitry and is suitable for composite video applications. FMS6414 dual-channel unit has second channel for Chroma signal and is suited for S-Video applications.
Original Press Release:
Single And Dual Video Line Drivers With Integrated Filters Replace Discrete Components To Save Board Space, Reduce Cost
San Jose, Calif.-July 15, 2002- Fairchild Semiconductor International (NYSE: FCS) introduces the FMS6413 (single channel) and the FMS6414 (dual channel) video line drivers with integrated video low pass filters for standard definition composite and S-video applications. These monolithic devices combine 75 ohm cable drivers with integrated filters, allowing them to remove artifacts introduced during D/A conversion in the encoder. These low-cost, space-saving devices replace discrete filters and line drivers in CCTV, set top box, DVD player, video camera and television applications.
The FMS6413 is a single channel filter-driver. It features 1.0dB flatness across the pass band, a 7.1 MHz cutoff frequency, and 37 dB stop-band rejection at 27 MHz. The filter approximates the performance of a 4th order Butterworth filter with an optimization toward low overshoot and flat group delay. The driver is capable of driving 2Vp-p into a 150 ohm load and offers less than 0.4% differential gain and 0.4% differential phase for the video signal. The FMS6413 is ideally suited for composite video applications where only a single video signal is involved. This monolithic device includes DC restore/sync-tip clamp circuitry for proper operation.
The FMS6414 is a dual channel filter-driver. It has the same filter characteristics as the single filter FMS6413, but adds the flexibility of a second channel that is generally used for the Chroma signal. The FMS6414 is perfectly suited for S-Video and other similar applications where the chrominance (chroma) and luminance (luma) are separated.
Both the FMS6413 and the FMS6414 are offered in a space- and cost-saving 8-pin SOIC package.
Price: FMS6413 is U.S. $0.79 and the FMS6414 is U.S. $0.91 (1,000 pcs.)
Delivery: 4 weeks ARO
