- IQ Matched ADC Pair
- 10-bit Resolution
- 1 MHz to 50 MHz Sampling Rate
- S/H stage for wide input common mode range
- 1.2V ±10% Analog and Digital Supply
- 2.5 V to 3.6V Analog Power Supply for the input interface
- Power Dissipation: 12mW @ 8.2Msps
- Power Dissipation: 31mW @ 30Msps
- Flexible power-down modes

This I&Q ADC IP core is also available in 90nm CMOS upon request.
The following block diagram illustrates the CI3611ul:
It is composed of a dual fully differential high speed low-power pipelined ADC core suitable for receive channels in I&Q configuration.
Dedicated S/H circuits are built-in to provide direct DC coupling with common mode voltage from 0.5V to 2V, and offering an optional single-ended to fully differential conversion.
The reference voltages are internally generated from an internal bandgap reference, with outside connection for decoupling purposes.
A power down capability is included for extremely low power dissipation in stand-by mode.
Silicon shows outstanding signal to noise ratio:
... and outstanding linearity:
This I&Q ADC is very suitable for any baseband front end in communication systems. It is optimized for low power applications requiring medium resolution and high-speed conversion rates, such as video, imaging, data acquisition, high-speed data reception and communications.
For SoC integration, Chipidea offers a wide range of Analog-Digital Interface Systems for Audio, Video, Multimedia, Data-Communications and Connectivity, including Power and Clock Management functions.
