ADC34J43IRGZT

四通道、14 位、80MSPS 模数转换器 ADC 48-VQFN -40 to 85

The ADC34J4x is a high-linearity, ultra-low power, quad-channel, 14-bit, 50-MSPS to 160-MSPS, analog-to-digital converter ADC. The devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. A clock input divider allows more flexibility for system clock architecture design while the SYSREF input enables complete system synchronization. The ADC34J4x family supports serial current-mode logic CML and JESD204B interfaces in order to reduce the number of interface lines, thus allowing high system integration density. The JESD204B interface is a serial interface, where the data of each ADC are serialized and output over only one differential pair. An internal phase-locked loop PLL multiplies the incoming ADC sampling clock by 20 to derive the bit clock that is used to serialize the 14-bit data from each channel. The ADC34J4x devices support subclass 1 with interface speeds up to 3.2 Gbps.
