Triple, 35MHz, 6th Order, HDTV Video Filter Driver
BL1516
Description
The BL1516 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, BL1516 can improve image quality. And it is ideally suited for battery
powered applications, because the BL1516 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 BL1516 by DC-coupled or AC-coupled
ways. Internal diode clamps and bias circuitry may be used if AC-coupled inputs are required. BL1516
also integrates an internal level shift circuit which avoids sync-pulse being clipped and allows DC-
coupled output. The driver in BL1516 can drive DC or AC-coupled single (150Ω) or dual (75 Ω) loads.
