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.
