DALLAS, Sept. 27 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced two new fully
integrated analog front ends (AFEs) with a continuous wave (CW)
Doppler mixer for mid- to high-end, Spectral Doppler ultrasound
equipment [view video]. The AFE5807 and AFE5808 address ultrasound
designers' need for superior performance and image quality with the
best noise performance at 0.75 nV/rtHz. In addition, the integrated
CW mode measures and displays blood flow velocity in ultrasound
images. These new devices are 25 percent smaller than
competing solutions, ensuring a compact system footprint for higher
channel count. For more information and to order AFE5807 and
AFE5808 samples, visit www.ti.com/ultrasound-pr.
Additional key features and benefits of the AFE5807 and the
AFE5808
- Integrated CW Doppler mixer and summing amplifier with a very
low close-in phase noise better than -155 dBc/Hz at 1 KHz off a 2.5
MHz carrier to ease design with CW beamforming.
- AFE5807 is a low-power solution with 88 mW/Ch at 1.1 nV/rtHz,
40 MSPS, 12-bit sampling.
- AFE5808 is a high-performance solution with low-noise
optimization of 0.75 nV/rtHz, 149 mW/ch, 65 MSPS and a 14-bit
analog-to-digital converter (ADC) with 77 dBFS SNR (signal-to-noise
ratio).
- Both integrate eight channels of the following components:
- Low-noise amplifier (LNA) with 24/18/12 dB gain settings to
enable 0.25/0.5/1 Vpp linear input range. 50, 100, 200 or 400 ohm
active termination supports a range of input amplitudes for
different class of transducers.
- Voltage controlled attenuator (VCA) and programmable gain
amplifier (PGA) with a total max gain of 54 dB for superior dynamic
range.
- 3rd order linear phase low-pass filter (LPF) with selectable
bandwidth of 10, 15, 20, and 30 MHz.
- 12- and 14-bit ADC with LVDS output up to 65 MSPS.
- Programmable modes to optimize power and performance for
various imaging modes.
AFE5807 and AFE5808 extend TI's AFE58xx family of fully
integrated ultrasound analog front ends, including the AFE5805 and
AFE5804 for portable to mid-range ultrasound and the AFE5801 and
AFE5851 for handheld, ultra-portable ultrasound. All AFE58xx
devices are complemented on the transmit side by TI's TX810 T/R
switch and join TI's full portfolio of embedded processing, analog
and power management solutions for ultrasound applications,
allowing manufacturers to bring innovative ultrasound systems to
market faster.
Tools, availability and packaging
The AFE5807 and AFE5808 are sampling now in a 9-mm x 15-mm,
135-pin BGA package. The AFE5807 is priced at $62 and the AFE5808 at $68, both in 1,000-unit quantities.
