Serial LVDS data outputs reduce the number of interface lines, resulting in a compact 64-pin QFN package (9 mm × 9 mm) that allows for high system integration density. The device includes 3.5dB coarse gain option that can be used to improve SFDR performance with little degradation in SNR. In addition to the coarse gain, fine gain options also exist, programmable in 1dB steps up to 6dB. The output interface is 2-wire, where each ADC data is serialized and output over two LVDS pairs. This makes it possible to halve the serial data rate (compared to a 1-wire interface) and restrict it to less than 1Gbps easing receiver design. 4通道,14位,105MSPS 模数转换器IC ADS6444IRGCT的特性 Maximum Sample Rate: 125 MSPS 14-Bit Resolution with No Missing Codes Simultaneous Sample and Hold 3.5dB Coarse Gain and up to 6dB Programmable Fine Gain for SFDR/SNR Trade-Off Serialized LVDS Outputs with Programmable Internal Termination Option Supports Sine, LVCMOS, LVPECL, LVDS Clock Inputs and Amplitude down to 400 mVPP Internal Reference with External Reference Support No External Decoupling Required for References 3.3-V Analog and Digital Supply 64 QFN Package (9 mm × 9 mm) Pin Compatible 12-Bit Family (ADS642X - SLAS532A) Feature Compatible Dual Channel Family (ADS624X - SLAS542A, ADS644X - SLAS543A) APPLICATIONS Base-Station IF Receivers Diversity Receivers Medical Imaging Test Equipment 4通道,14位,105MSPS 模数转换器IC ADS6444IRGCT的应用   基站 IF 接收器   多样性接收器   医学影像   测试设备
