三路数模转换器 DAC CDK340
General Description
CDK3400/3401 products are low-cost triple D/A converters that are tailored
to fit graphics and video applications where speed is critical. Two speed
grades are available: CDK3400 at 100MSPS and CDK3401 at 150MSPS.
TTL-level inputs are converted to analog current outputs that can drive
25-37.5Ω loads corresponding to doubly-terminated 50-75Ω loads. A sync
current following SYNC input timing is added to the IOG output. BLANK
will override RGB inputs, setting IOG, IOB and IOR currents to zero when
BLANK = L. Although appropriate for many applications, the internal 1.235V
reference voltage can be overridden by the VREF input.
Few external components are required, just the current reference resistor,
current output load resistors, and decoupling capacitors.
Package is a 48-lead TQFP. Fabrication technology is CMOS. Performance is
guaranteed from 0 to 70°C.
CADEKA发布了一个数模转换器(DAC)产品族,包括8位和10位、三路,采样率从100到180MSPS的产品;它们是CDK3400/CDK3401,CDK3402/CDK3403和CDK3404。这些高速数模(D/A)转换器是专为视频、显示以及图像应用而优化设计的。其中,8位的CDK3404提供180MSPS的采样率,使它非常适合应用于60Hz VGA(6?0 x 480)、72Hz SVGA(800 x 600)、75Hz XGA(1024 x 768)、以及60Hz SXGA(1280 x 1024)等多种显示标准。它可以支持对RGB、YCBCR、以及混合YC信号进行视频信号转换。
CDK3403工作于3.3V单电源,其内部包含了双电平同步和消隐电平发生电路。这个电流驱动的数模转换器(DAC)被明确的设计为用来直接在两端都有端接的传输单端信号的75Ω同轴电缆上产生标准视频输出电平。
高分辨率,易于使用,加上扩展的温度范围:-40°C to +125°C使得CDK3404成为很多视频应用的不二之选,比如LCD显示器、医用超声、车载娱乐、超便携个人电脑(UMPC)、mini-USB到VGA连接器、以及其它多媒体系统。
