UNISONIC TECHNOLOGIES CO., LTD VF8143 Preliminary CMOS IC LOW-COST Three-Channel 4TH-ORDER STANDARDDEFINITION VIDEO FILTERS DESCRIPTION The UTC VF8143 Low-Cost Video Filter (LCVF) offers three channels of 4th-order filters for standard-definition and drivers with a low-cost integrated device. The UTC VF8143 inputs feature a transparent clamp compatible with AC- coupled and DC-coupled input signals and allows DAC outputs to be directly coupled. The outputs can drive AC- or DC-coupled single (150Ω) or dual (75Ω) loads. The input DC levels are offset approximately +280mV at the output (see Applications section for details). The UTC VF8143 is ideal for DAC smoothing in applications such as cable set-top boxes, satellite set-top boxes, HDTV, video on demand (VOD), DVD players, and personal video recorders. SOP-8 FEATURES * Three-Channel 4th-order 8MHz filters for SD video * Transparent input clamping * AC-or DC-coupled inputs * AC-or DC-coupled outputs * Drives single, +6dB output (150Ω) * Drives dual, +6dB output (75Ω) * DC-coupled outputs eliminate AC-coupling capacitors * Single +5V power supply * Robust 8kV ESD protection ORDERING INFORMATION Ordering Number Lead Free Halogen Free VF8143L-S08-R VF8143GS08-R www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd Package Packing SOP-8 Tape Reel 1 of 4 QW-R502-956.b VF8143 Preliminary MARKING PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME IN1 IN2 IN3 VCC GND OUT3 OUT2 OUT1 CMOS IC DESCRIPTION Video input, Channel 1 Video input, Channel 2 Video input, Channel 3 +5V supply, do not float Must be tied to ground, do not float Filtered output, Channel 3 Filtered output, Channel 2 Filtered output, Channel 1 BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 4 QW-R502-956.b VF8143 Preliminary CMOS IC ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT DC Supply Voltage VCC -0.3~6 V Analog and Digital I/O -0.3~VCC+0.3 V Output Channel-Any One Channel (Do Not Exceed) 50 mA Junction Temperature TJ +150 °C Operating Temperature TOPR -40~+85 °C Storage Temperature TSTG -65~+150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
