SD9643-170

14-bit, 170MHz, Dual Channel ADC

Overview & Features

The SD9643 is a dual-channel, 14-bit, analog-to-digital converter (ADC) supporting sampling rates up to 170MSps. The device uses a multistage pipeline architecture to achieve high signal-to-noise ratio (SNR) and linearity, over wide input signal bandwidth. The SD9643 uses a LVDS 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: 73.9dBFS at fIN = 70.2MHz and fS = 170MSps

* -155.2dBFS/Hz input-noise at fIN = 70.2MHz and fS = 170MSps
* 2.0V nominal input
* Typical power consumption: 495mW at 170MSps
* Integer 1-to-8 input clock divider (1000MHz maximum input rate)
* Sample rates of up to 170MSps
* 1.8V analog supply voltage
* LVDS (ANSI-644 levels) outputs
* Internal ADC voltage reference
* ADC clock duty cycle correction
* Serial port control
* Energy saving power-down modes
