The SGM9123 is a rail-to-rail, triple 3rd-order output reconstruction filter which can operate from 2.5V to 5.5V single power supply. Compared with typical passive solutions, triple 3rd-order filters provide better image quality.
The device has a -3dB bandwidth of 8MHz and 44V/µs slew rate. The drivers in SGM9123 can drive DC- or AC-coupled single (150Ω) or dual (75Ω) loads.
The device allows DC-coupled output. An internal level shift circuit avoids synchronous pulse limit. SGM9123 can be DC-coupled or AC-coupled with input video signal to eliminate out-of-band noise, such as the output stage of DAC. Internal clamp and bias circuitry may be used if AC-coupled inputs are required.
The SGM9123 is available in a Green SOIC-8 package.
