UNISONIC TECHNOLOGIES CO., LTD VF8418 Preliminary CMOS IC TRIPLE VIDEO DRIVER WITH SELECTABLE HD/SD VIDEO FILTERS FOR RGB OR YUV SIGNALS DESCRIPTION The UTC VF8418 consists of a triple 6th order filter with selectable 30MHz or 8.0MHz frequencies. The triple filters are intended for either YUV or RGB signals. There is a 2-to-1 multiplexer in each filter channel. All channels accept DC coupled ground-referenced 1V signals. The filters provide 2Vpp signals into AC coupled terminated loads. The low-pass filters are powered by 3.3V and the outputs by 5.0V. The UTC VF8418 offers comprehensive filtering for cable set-top boxes, satellite set-top boxes, HDTV, video on demand (VOD), personal video recorders, or DVD applications. FEATURES * Three video anti-aliasing or reconstruction filters * 2:1 Mux inputs for multiple RGB/YUV inputs * Selectable 8MHz or 30MHz 6th order filters for SD/HD applications * DC coupled input, AC coupled output * Drives single, +6dB output AC coupled 150Ω loads * 0.6% differential gain with 0.15° differential phase * 36dB/octave roll-off on all channels ORDERING INFORMATION Ordering Number Lead Free Halogen Free VF8418L-D16-T VF8418G-D16-T Package Packing DIP-16 Tube VF8418L-S08-T (1)Packing Type (1) T: Tube (2)Package Type (2) D16: DIP-16 (3)Lead Free (3) L: Lead Free, G: Halogen Free www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 6 QW-R502-944.a VF8418 Preliminary CMOS IC PIN CONFIGURATION INMUX 1 16 FSEL RINA 2 15 VSSA RINB 3 14 VSSO GINA 4 13 ROUT GINB 5 12 GOUT BINA 6 11 BOUT BINB 7 10 VCCO NC 8 9 VCCA VF8418 PIN DESCRIPTION PIN NO.
