SD1148ET-125

The SD1148ET is a dual-channel, 14-bit, analog-to-digital converter (ADC) supporting sampling rates up to 125MSps. The
SD1148ET supports an extended temperature range of -55°C to 125°C. The device uses a multistage pipeline
architecture to achieve high signal-to-noise ratio (SNR) and linearity, over wide input signal bandwidth. The SD1148ET
can be set to operate using either CMOS or LVDS output interface. 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.

The device includes a DSP block that features decimation, digital down conversion (DDC), and IQ mismatch correction.
