Description
This product is a 4-channel, 14-bit Analog-to-Digital Converter (ADC) with a sampling rate of 125MSPS. It is specifically developed and designed for low power consumption, small size, andflexibility in use. The product can achieve a maximum conversion rate of 125 MSPS, boastingexcellent dynamic performance and ultra-low power consumption, which makes it suitable for a wide range of application scenarios.
This ADC is powered by a single 1.8V power supply and accepts sampling clock signals compatible with LVPECL, CMOS, and LVDS.It can meet the requirements without the need for an external reference voltage source or driver.
It supports the function of independently turning off each internal channel. When all channelsare disabled, the typical power consumption is less than 14 mW. This ADC is equipped withvarious built-in functions, such as programmable clock output, data alignment, and thegeneration of digital test codes. The available digital test codes include built-in fixed test codesand pseudo-random test codes. It also allows users to customize test codes via the Serial PortInterface (SPI).
This product comes in a 48-pin QFN48 package. The rated operating temperature range of thisADC is from -40°C to +85°C.
This product can be plug-and-play replaced with the AD9253 of Analog Devices, Inc. (ADI) in theUnited States.
