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

1.8 V Analog-to-Digital Converter

Data Sheet

AD9255

FEATURES

APPLICATIONS

SNR = 78.3 dBFS at 70 MHz and 125 MSPS

SFDR = 93 dBc at 70 MHz and 125 MSPS

Low power: 371 mW at 125 MSPS

Communications

Multimode digital receivers (3G)

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

TD-SCDMA

1.8 V analog supply operation

1.8 V CMOS or LVDS output supply

Smart antenna systems

Integer 1-to-8 input clock divider

General-purpose software radios

Broadband data applications

Ultrasound equipment

IF sampling frequencies to 300 MHz

−153.4 dBm/Hz small signal input noise with 200 Ω input

impedance at 70 MHz and 125 MSPS

Optional on-chip dither

PRODUCT HIGHLIGHTS

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 DCS, power-down, test modes, and voltage

reference mode.

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

Serial port control

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

Energy-saving power-down modes

5. Pin compatibility with the AD9265, allowing a simple

migration up to 16 bits.
