CN3333中文资料Three-channel 6th-Order High Definition Video Filter Driver数据手册ChipNext规格书

描述 Description

The CN3333 low voltage, three-channel 6th order HD video filter is intended to replace passive LC filter and drivers with a low-cost integrated device. The CN3333 can be directly driven by a DC coupled DAC output or an AC coupled signal. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required. The output can drive AC or DC coupled single (150Ω) or dual (75Ω) loads. DC coupling the outputs removes the need for output coupling capacitors.

特性 Features

• Integrated 6th-order, 30MHz filters
• Fixed 6dB
• Operates from 3.1V – 5V supply
• Low supply current – 8mA per channel
• AC or DC coupled inputs
• AC or DC coupled outputs
• Capable of driving 2Vpp into 1 or 2 video loads (150Ω or 75Ω)
