Three-channel fourth-order video filter IC

   FMS6143 internally integrates a fourth-order low-pass filter and a 2dB gain amplifier, which can replace the passive LC filter circuit. Due to the integrated internal diode clamp circuit and bias circuit, the DAC output signal can be DC or AC coupled to the FMS6143. Its output can be DC coupled (150Ω load) or AC coupled output. When the input bias is 0, the lowest output level is +300mV.

FEATUREs
1) Three-channel fourth-order 8MHz filter 
2) AC or DC coupled output driver 
3) Built-in transparent input clamp circuit width 
4)AC or DC coupled input 8)SOIC8 package
5) DC-coupled output can reduce off-chip AC capacitance
6) 3.3V or 5V power supply
7) 8kVESD protection

APPLICATIONs
   Optical transceivers, satellite TV set-top boxes, DVDs, HDTVs, cameras and video recorders
