Monitors
DESCRIPTION
The CVA2417TX is an improved version that features
excellent gray scale linearity with no crossover distortion and
less EMI. Designed especially to drive high resolution monitor
for resolution up to 1280 x 1024 (non-interlaced) with pixel
frequency up to 160MHz.
The part is housed in the industry standard 11-lead TO-220
molded power package. The heat sink is floating and may be
grounded for ease of manufacturing and RFI shielding.
