Overview & Features

The SD9251 is a dual-channel, 14-bit, analog-to-digital converter (ADC) supporting sampling rates up to 65MSps. The
device uses a multistage pipeline architecture to achieve high signal-to-noise ratio (SNR) and linearity, over wide input
signal bandwidth. The SD9251 uses a CMOS output interface to transfer the data out. Programming for configuration and
control is accomplished using a 3-wire SPI-compatible serial bus. The digital output data can be programmed to be
delivered in offset binary, twos complement format, or gray code.

FEATURES

  • SNR: 74.8dBFS at fIN = 30.2MHz and fS = 65MSps
  • SFDR: 91.0dBc at fIN = 30.2MHz and fS = 65MSps
  • -151.5dBFS/Hz input-noise at fIN = 30.2MHz and fS =
    65MSps
  • 2.0Vp-p nominal input
  • Typical power consumption: 335mW at 65MSps
  • Integer 1-to-8 input clock divider (520MHz maximum
    input rate)
  • Sample rates of up to 65MSps
  • 1.8V analog supply voltage
  • Up to 3.3V digital I/O supply voltage
  • Internal ADC voltage reference
  • ADC clock duty cycle correction
  • Serial port control
  • Energy saving power-down modes
