AFE5808AZCF Beschreibung

The AFE5808AZCF is a highly-integrated, analog front-end (AFE) solution specifically designed for ultrasound systems in which high performance and small size are required. The AFE5808AZCF integrates a complete time-gain-control (TGC) imaging path and a continuous wave Doppler (CWD) path. This device also enables users to select one of various power and noise combinations to optimize system performance. Therefore, the AFE5808AZCF is an outstanding ultrasound analog front-end solution not only for high-end systems, but also for portable ones.

The AFE5808AZCF device contains eight voltage controlled amplifiers (VCA), 14- and 12-bit analog-to-digital converters (ADC), and CW mixers. The VCA includes a 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 ultralow noise VCAT provides an attenuation control range of 40 dB, and improves overall low gain SNR that benefits harmonic imaging and near field imaging. The PGA provides gain options of 24 dB and 30 dB. In front of 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 AFE5808AZCF device achieves 77-dBFS SNR, and ensures excellent SNR at low-chain gain. The ADC LVDS outputs enable flexible system integration desired for miniaturized systems.

The AFE5808AZCF device also incorporates a low-power passive mixer and a low-noise summing amplifier to accomplish on-chip CWD beamforming. Sixteen selectable phase-delays can be applied to each analog input signal. A unique 3rd- and 5th-order harmonic-suppression filter is implemented to enhance CW sensitivity.

The AFE5808AZCF is available in a 15-mm × 9-mm, 135-pin BGA package and it is specified for operation from 0°C to 85°C. This device is also pin-to-pin compatible with the AFE5803, AFE5807, and AFE5808.

NOTE: The AFE5808AZCF is an enhanced version of AFE5808 and is recommended for new designs. Compared to the AFE5808, the AFE5808AZCF expands the cutoff frequency range of the digital high-pass filter; increases the handling capability of extreme overload signals; and lowers the correlated noise significantly when high-impedance source appears.
