ADC1113D125
Dual 11-bit ADC; serial JESD204A interface
Rev. 02 — 23 April 2010
Preliminary data sheet
1. General description
The ADC1113D125 is a dual-channel 11-bit Analog-to-Digital Converter (ADC) optimized
for high dynamic performances and low power at sample rates of 125 Msps. Pipelined
architecture and output error correction ensure the ADC1113D125 is accurate enough to
guarantee zero missing codes over the entire operating range. Supplied from a 3 V
source for analog and a 1.8 V source for the output driver, it embeds two serial outputs.
Each lane is differential and complies with the JESD204A format. An integrated Serial
Peripheral Interface (SPI) allows the user to easily configure the ADC. A set of IC
configurations is also available via the binary level control pins taken, which are used at
power-up. The device also includes a SPI programmable full-scale to allow flexible input
voltage range from 1 V to 2 V (peak-to-peak).
Excellent dynamic performance is maintained from the baseband to input frequencies of
170 MHz or more, making the ADC1113D125 ideal for use in communications, imaging,
and medical applications.
