What are the key features of TLV990-28?

  • 28 Msps 10-bit sampling rate enables real-time digitization of signals up to 14 MHz bandwidth in ultrasound, medical imaging, and communications receiver front-ends
  • Dual parallel and serial output interface support allows flexible integration with FPGAs, DSPs, and microcontrollers without an external serializer
  • 48-pin TQFP package integrates analog front-end signal conditioning and ADC in a single 7 mm × 7 mm footprint, reducing BOM complexity in high-speed data acquisition designs

What is TLV990-28 used for?

TLV990-28 is designed for high-speed analog-to-digital conversion in applications such as portable ultrasound equipment, software-defined radio (SDR) receivers, medical diagnostic instruments, and industrial non-destructive testing systems. Its 28 Msps conversion rate and 10-bit resolution support digitizing intermediate frequency (IF) signals up to 14 MHz bandwidth with adequate dynamic range for imaging and communications. The dual parallel and serial output modes provide direct interfacing to FPGAs, DSPs, and application processors in compact high-speed data acquisition boards.

Frequently Asked Questions

What is the maximum sample rate of TLV990-28 and what signal bandwidth does it support for data acquisition?

TLV990-28 achieves a maximum sample rate of 28 Msps with 10-bit resolution, enabling digitization of analog input signals with bandwidth up to approximately 14 MHz according to the Nyquist criterion. This throughput is well matched to intermediate frequency (IF) sampling in software-defined radio receivers at 10 MHz IF, portable ultrasound probes operating in the 5 MHz to 10 MHz frequency range, and narrowband radar signal processors.

What output interface options does TLV990-28 provide and how do they integrate with FPGAs or DSPs?

TLV990-28 supports both parallel and serial digital output interfaces, allowing designers to select the most suitable bus for the host processor. The parallel interface delivers 10-bit data on a wide bus for direct connection to FPGA I/O banks without serialization latency, while the serial interface reduces pin count for connection to MCU or DSP SPI ports on space-constrained PCBs. Both interfaces operate at the 28 Msps conversion rate, enabling real-time streaming of 10-bit samples to the digital processing chain.

For a portable ultrasound design, what advantages does TLV990-28 offer over lower-speed ADC alternatives at 10 Msps?

TLV990-28's 28 Msps conversion rate provides nearly 3x the oversampling margin compared to a 10 Msps ADC when digitizing a 5 MHz ultrasound transducer signal. This oversampling enables higher effective resolution through digital decimation filters, achieving up to 12 bits of effective number of bits (ENOB) from the 10-bit core, and permits sharper anti-aliasing filter designs with higher cutoff frequencies that reduce analog filter component cost and phase distortion in the ultrasound receive path.

What package does TLV990-28 use and what does it imply for PCB thermal and layout design?

TLV990-28 is housed in a 48-pin TQFP measuring 7 mm × 7 mm with a 0.5 mm pin pitch, a standard surface-mount footprint supported by common PCB layout tools. High-speed ADC layouts should route analog and digital power planes separately with dedicated 100 nF decoupling capacitors on each power pin, and avoid running digital clock or data lines beneath the analog input traces to prevent signal contamination at the 28 Msps conversion rate.
