CHIPIDEA´s 0.13µm Low Power I&Q ADC designed for DVB-H/DMB systems excels in Silicon

CHIPIDEA´s 0.13µm Low Power 10-bit I&QADC was designed for Handheld Digital TV receivers supporting the emerging DVB-H video standard. This is an excellent Analog-to-Digital interface for receivers in portable systems, such as PDAs, phones, and PMPs. The CI3611ul is successfully embedded in an application specific SoC.

Brief Description

Main Features

• 0.13 µm CMOS, 1P6M, no analog options

• 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

• Core Cell Area: 1.0 mm2

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.
