Figure 1

The AD9262 incorporates an integrated dc correction and

quadrature estimation block that corrects for gain and phase

mismatch between the two channels. This functional block

proves invaluable in complex signal processing applications

such as direct conversion receivers.

Serial control interface (SPI)

APPLICATIONS

The digital output data is presented in offset binary, Gray code,

or twos complement format. A data clock output (DCO) is

provided to ensure proper timing with the receiving logic. The

AD9262 has the added feature of interleaving Channel A and

Channel B data onto one 16-bit bus, simplifying on-board routing.

Baseband quadrature receivers: CDMA2000, W-CDMA,

multicarrier GSM/EDGE, 802.16x, and LTE

Quadrature sampling instrumentation

Medical equipment

Radio detection and ranging (RADAR)

The ADC is available in three different bandwidth options of

2.5 MHz, 5 MHz, and 10 MHz, and operates on a 1.8 V analog

supply and a 1.8 V to 3.3 V digital supply, consuming 600 mW.

The AD9262 is available in a 64-lead LFCSP and is specified

over the industrial temperature range (−40°C to +85°C).

GENERAL DESCRIPTION

The AD9262 is a dual channel, 16-bit analog-to-digital conver-

ter (ADC) based on a continuous time (CT) sigma-delta (Σ-Δ)

architecture that achieves −87 dBc of dynamic range over a

10 MHz input bandwidth. The integrated features and characteris-

tics unique to the continuous time Σ-Δ architecture significantly

simplify its use and minimize the need for external components.

PRODUCT HIGHLIGHTS

1. Continuous time Σ-Δ architecture efficiently achieves high

dynamic range and wide bandwidth.

The AD9262 has a resistive input impedance that relaxes the

requirements of the driver amplifier. In addition, a 32× oversam-

pled fifth-order continuous time loop filter significantly attenuates

out-of-band signals and aliases, reducing the need for external

filters at the input.

2. Passive input structure reduces or eliminates the require-

ments for a driver amplifier.

3. An oversampling ratio of 32× and high order loop filter

provide excellent alias rejection reducing or eliminating the

need for antialiasing filters.

4. An integrated decimation filter, sample rate converter, PLL

clock multiplier, and voltage reference provide ease of use.

5. Integrated dc correction and quadrature error correction.

6. Operates from a single 1.8 V analog power supply and

1.8 V to 3.3 V output supply.

An external clock input or the integrated integer-N PLL provides

the 640 MHz internal clock needed for the oversampled conti-

nuous time Σ-Δ modulator. On-chip decimation filters and sample

rate converters reduce the modulator data rate from 640 MSPS to a

user-defined output data rate between 30 MSPS and 160 MSPS,

enabling a more efficient and direct interface.
