Octal LNA/VGA/AAF/14-Bit ADC

and CW I/Q Demodulator

AD9277

FEATURES

APPLICATIONS

8 channels of LNA, VGA, AAF, ADC, and I/Q demodulator

Low noise preamplifier (LNA)

Medical imaging/ultrasound

Automotive radar

Input-referred noise: 0.75 nV/√Hz typical at 5 MHz

(gain = 21.3 dB)

PRODUCT HIGHLIGHTS

SPI-programmable gain: 15.6 dB/17.9 dB/21.3 dB

Single-ended input: V_INmaximum = 733 mV p-p/

550 mV p-p/367 mV p-p

Dual-mode active input impedance matching

Bandwidth (BW) > 100 MHz

Full-scale (FS) output: 4.4 V p-p differential

Variable gain amplifier (VGA)

Attenuator range: −42 dB to 0 dB

Postamp gain: 21 dB/24 dB/27 dB/30 dB

Linear-in-dB gain control

Antialiasing filter (AAF)

Programmable second-order LPF from 8 MHz to 18 MHz

Programmable HPF

Analog-to-digital converter (ADC)

14 bits at 10 MSPS to 50 MSPS

SNR: 73 dB

SFDR: 75 dB

Serial LVDS (ANSI-644, IEEE 1596.3 reduced range link)

Data and frame clock outputs

CW mode I/Q demodulator

1. Small Footprint.

Eight channels are contained in a small, space-saving

package. Full TGC path, ADC, and I/Q demodulator

contained within a 100-lead, 16 mm × 16 mm TQFP.

2. Low Power.

In TGC mode, low power of 207 mW per channel

at 50 MSPS. In CW mode, ultralow power of 94 mW

per channel.

3. Integrated High Dynamic Range I/Q Demodulator with

Phase Rotation.

4. Ease of Use.

A data clock output (DCO± ± operates up to 480 MHz

and supports double data rate (DDR± operation.

5. User Flexibility.

Serial port interface (SPI± control offers a wide range of

flexible features to meet specific system requirements.

6. Integrated Second-Order Antialiasing Filter.

This filter is placed before the ADC and is programmable

from 8 MHz to 18 MHz.

Individual programmable phase rotation

Output dynamic range per channel >160 dBFS/√Hz

Low power: 207 mW per channel at 14 bits/50 MSPS (TGC),

94 mW per channel for CW Doppler

Flexible power-down modes

Overload recovery in <10 ns

Fast recovery from low power standby mode: <2 μs
