DESCRIPTION
The AFE5807 is an integrated Analog Front-End
(AFE) solution specifically designed for ultrasound
systems in which high performance and small size
are required. The AFE5807 integrates a complete
time-gain-control (TGC) imaging path and a
continuous wave Doppler (CWD) path. It also enables
users to select one of various power/noise
combinations to optimize system performance.
Therefore, the AFE5807 is a suitable ultrasound
analog front end solution not only for high-end
systems, but also for portable systems.
The AFE5807 contains eight channels of voltage
controlled amplifier (VCA), 12-bit Analog-to-Digital
Converter (ADC), and CW mixer. The VCA includes
Low noise Amplifier (LNA), Voltage controlled
Attenuator(VCAT), Programmable Gain Amplifier
(PGA), and Low-Pass Filter (LPF). The LNA gain is
programmable to support 250 mVPP to 1 VPP input
signals. Programmable active termination is also
supported by the LNA. The ultra-low noise VCAT
provides an attenuation control range of 40 dB 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 12
bit/80 MSPS ADC in the AFE5807 achieves 70 dBFS
SNR. It ensures excellent SNR at low chain gain. The
ADC’s LVDS outputs enable flexible system
integration desired for miniaturized systems. The
AFE5807 also integrates a low power passive mixer
and a low noise summing amplifier to accomplish onDoppler(
chip CWD beamformer. 16 selectable phase-delays
can be applied to each analog input signal.
Meanwhile a unique 3rd and 5th order harmonic suppression filter is implemented to enhance CW
sensitivity.
The AFE5807 is available in a 15mm × 9mm, 135-pin
BGA package and it is specified for operation from
0°C to 85°C. It is also pin-to-pin compatible to the
AFE5808, AFE5803, and AFE5808A. In addtion, AFE5809 is another member with enhanced digital
demodulation features in this family.
