The CXVD3321 is a video buffer which integrates triple 6dB Gain
rail-to-rail output driver and triple 6th order output reconstruction
filter, and it owns 35MHz -3dB bandwidth. Compared with passive LC
filters and discrete drivers, CXVD3321 can improve image quality. And
it is ideally suited for battery powered applications, because the
CXVD3321 can operate under the environment with single supplies ranging
from +3.3V to +5.5V and sinking an ultra-low 36mA quiescent current

一.产品概述
The CXVD3321 is a video buffer which integrates triple 6dB Gain rail-to-rail output driver and triple 6th order output reconstruction filter, and it owns 35MHz -3dB bandwidth. Compared with passive LC
filters and discrete drivers, CXVD3321 can improve image quality. And it is ideally suited for battery powered applications, because the CXVD3321 can operate under the environment with single supplies ranging
from +3.3V to +5.5V and sinking an ultra-low 36mA quiescent current. Video signal, such as the output of DAC, can be input in the CXVD3321 by DC-coupled or AC-coupled ways. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required. CXVD3321 also integrates an internal level shift circuit which avoids sync-pulse being clipped and allows DCcoupled output. The driver in CXVD3321 can drive DC or AC-coupled single (150Ω) or dual (75 Ω) loads.
