UNISONIC TECHNOLOGIES CO., LTD VF8146 Preliminary CMOS IC LOW-COST SIX-CHANNEL 4TH-ORDER STANDARDDEFINITION VIDEO FILTERS DESCRIPTION The UTC VF8146 Low-Cost Video Filter (LCVF) offers six channels of 4th-order filters for standard-definition and drivers with a low-cost integrated device. The UTC VF8146 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 VF8146 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. FEATURES * Six-Channel 4th-order 8MHz filters for standard-Definition 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 ORDERING INFORMATION Ordering Number Lead Free Halogen Free VF8146L-P14-R VF8146G-P14-R VF8146L-P14-T VF8146G-P14-T VF8146L-P14-T Package Packing TSSOP-14 TSSOP-14 Tape Reel Tube (1)Packing Type (1) T: Tube, R: Tape Reel (2)Package Type (2) P14: TSSOP-14 (3)Halogen Free (3) L: Lead Free, G: Halogen Free www.unisonic.com.tw Copyright © 2013 Unisonic Technologies Co., Ltd 1 of 5 QW-R502-945.a VF8146 Preliminary PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 PIN NAME IN1 IN2 IN3 VCC IN4 IN5 IN6 OUT6 OUT5 OUT4 GND OUT3 OUT2 OUT1 CMOS IC DESCRIPTION Video input, Channel 1 Video input, Channel 2 Video input, Channel 3 +5V Power Supply, do not float Video input, Channel 4 Video input, Channel 5 Video input, Channel 6 Filtered video output, Channel 6 Filtered video output, Channel 5 Filtered video output, Channel 4 Ground, do not float Filtered video output, Channel 3 Filtered video output, Channel 2 Filtered video output, Channel 1 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R502-945.a VF8146 Preliminary CMOS IC BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 3 of 5 QW-R502-945.a VF8146 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.
