SLOS688C –SEPTEMBER 2010–REVISED APRIL 2012

Fully Integrated, 8-Channel Ultrasound Analog Front End with Passive CW Mixer,

0.75nV/rtHz, 14/12-Bit, 65MSPS, 153mW/CH

Check for Samples: AFE5808

FEATURES

APPLICATIONS

•

8-Channel Complete Analog Front-End

LNA, VCAT, PGA, LPF, ADC, and CW Mixer

•

•

Nondestructive Evaluation Equipments

DESCRIPTION

•

Programmable Gain Low-Noise Amplifier

(LNA)

The AFE5808 is a highly integrated Analog Front-End

(AFE) solution specifically designed for ultrasound

systems in which high performance and small size

are required. The AFE5808 integrates a complete

–

24/18/12 dB Gain

0.25/0.5/1 V_PPLinear Input Range

0.63/0.7/0.9 nV/rtHz Input Referred Noise

Programmable Active Termination

time-gain-control (TGC) imaging path and

continuous wave Doppler (CWD) path. It also enables

users to select one of various power/noise

combinations to optimize system performance.

Therefore, the AFE5808 is a suitable ultrasound

analog front end solution not only for high-end

systems, but also for portable ones.

•

40 dB Low Noise Voltage Controlled

Attenuator (VCAT)

•

24/30 dB Programmable Gain Amplifier (PGA)

3^rdOrder Linear Phase Low-Pass Filter (LPF)

The AFE5808 contains eight channels of voltage

controlled amplifier (VCA), 14/12-bit Analog-to-Digital

Converter (ADC), and CW mixer. The VCA includes

Low noise Amplifier(LNA), Voltage controlled

–

10, 15, 20, 30 MHz

•

14-bit Analog to Digital Converter (ADC)

–

77 dBFS SNR at 65 MSPS

LVDS Outputs

Attenuator(VCAT),

Programmable

Gain

Amplifier(PGA), and Low-Pass Filter (LPF). The LNA

gain is programmable to support 250 mV_PPto 1 V_PP

input signals. Programmable active termination is

also supported by the LNA. The ultra-low noise VCAT

provides an attenuation control range of 40dB and

improves overall low gain SNR which benefits

harmonic imaging and near field imaging. The PGA

provides gain options of 24 dB and 30 dB. Before the

ADC, a LPF can be configured as 10 MHz, 15 MHz,

20 MHz or 30 MHz to support ultrasound applications

with different frequencies. The high-performance 14

bit/65 MSPS ADC in the AFE5808 achieves 77 dBFS

SNR. It ensures excellent SNR at low chain gain. The

ADC’s LVDS outputs enable flexible system

integration desired for miniaturized systems.

Noise/Power Optimizations (Full Chain)

–

153 mW/CH at 0.75 nV/rtHz, 65 MSPS

98 mW/CH at 1.1 nV/rtHz, 40 MSPS

80 mW/CH at CW Mode

•

Excellent Device-to-Device Gain Matching

±0.5 dB(typical) and ±0.9 dB(max)

–

•

Low Harmonic Distortion

Fast and Consistent Overload Recovery

Passive Mixer for Continuous Wave

Doppler(CWD)

–

Low Close-in Phase Noise –156 dBc/Hz at 1

KHz off 2.5 MHz Carrier

–

Phase Resolution of 1/16λ

Support 16X, 8X, 4X and 1X CW Clocks

12dB Suppression on 3^rdand 5^thHarmonics

Flexible Input Clocks

•

Small Package: 15 mm x 9 mm, 135-BGA

NOTE

AFE5808A is an enhanced version of AFE5808 and it is recommended for new designs.

Compared to AFE5808, it expands the cut-off frequency range of the digital high pass

filter; increases the handling capability of extreme overload signals; lowers the correlated

noise significantly when high impedance source appears.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
