16-Bit, 125 MSPS/105 MSPS/80 MSPS,

1.8 V Analog-to-Digital Converter

AD9265

FEATURES

PRODUCT HIGHLIGHTS

SNR = 79.0 dBFS @ 70 MHz and 125 MSPS

SFDR = 93 dBc @ 70 MHz and 125 MSPS

Low power: 373 mW @ 125 MSPS

1.8 V analog supply operation

1.8 V CMOS or LVDS output supply

Integer 1-to-8 input clock divider

IF sampling frequencies to 300 MHz

−154.3 dBm/Hz small signal input noise with 200 Ω input

impedance @ 70 MHz and 125 MSPS

Optional on-chip dither

Programmable internal ADC voltage reference

Integrated ADC sample-and-hold inputs

Flexible analog input range: 1 V p-p to 2 V p-p

Differential analog inputs with 650 MHz bandwidth

ADC clock duty cycle stabilizer

1. On-chip dither option for improved SFDR performance

with low power analog input.

2. Proprietary differential input that maintains excellent SNR

performance for input frequencies up to 300 MHz.

3. Operation from a single 1.8 V supply and a separate digital

output driver supply accommodating 1.8 V CMOS or

LVDS outputs.

4. Standard serial port interface (SPI) that supports various

product features and functions, such as data formatting

(offset binary, twos complement, or gray coding), enabling

the clock duty cycle stabilizer, DCS, power-down, test

modes, and voltage reference mode.

5. Pin compatibility with the AD9255, allowing a simple

migration from 16 bits down to 14 bits.

Serial port control

User-configurable, built-in self-test (BIST) capability

Energy-saving power-down modes

APPLICATIONS

Communications

Multimode digital receivers (3G)

GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX,

and TD-SCDMA

Smart antenna systems

General-purpose software radios

Broadband data applications
