Full band, High-Resolution Spectrum Analysis Solutions

STN93321 is a complete Total Spectrum Reception (TSR™ ) SOC with a unique patent pending technology for capturing, recording and analyzing spectrum utilizing Direct RF Sampling technology. STN93321 unlike its competition is a standalone solution that uses power measurement as a way of capturing spectrum while providing four resolution modes with bandwidths that can go up to 1.2GHz. This distinctive product can provide Full-Band Spectrum Monitoring, single channel and multi-channel monitoring as well as phase noise measurement depending on the selected resolution mode.

It can also detect impairments associated with Standing Waves, 4G LTE ingress, Roll-off, Adjacency and much more. This is achieved due to the unsurpassed level of integration that includes a high-performance wide band RF front-end, a multi-GS/s high resolution Analog-to-Digital Convertor and a complex Digital Signal Processing Unit for recording
spectrum.

Features

  • Integrated LNA, 3Gs/s ADC, Digital Spectrum Analyzer and low phase noise PLL on one Silicon
  • Linux/ARM optimized API library to enable various spectrum monitoring features such as SNR measurement, channel power measurement and impairment analysis.
  • Supports Main path and Aux path to measure downstream and upstream separately.
  • Integrated high speed DAC and integrated digital Cordic engine to generate desired CW tones for calibration applications.
  • Programmable spectrum analyzer resolution to capture the entire bandwidth at once or to zoom in to a single tone and measure phase noise
  • Integrated Smart AGC to handle different conditions in Cable/Terrestrial environments like Tilt and Adjacent channels.
  • STN93321 DS Spectrum monitoring can detect any impairments shown below in accordance with Section 2. Wideband Spectrum Analysis , Measurement item 5.2.6 Spectral Impairment Detection of the PNM standard CM-GL-PNM-3.1-V01-200506

Benefits

  • Provides a standalone platform for HW and SW which is independent from any Docsis processor.
  • Reduces cost of BOM for a spectrum analyzer platform to at least 20% by eliminating expensive standalone highspeed ADC and FPGA in an alternative solution.
  • A total power consumption of less than 2W as opposed to a minimum of 10W for an alternative solution.
  • Ready to use Linux/ARM optimized API library and with minimal SW integration effort.
  • 10×10, 88pin QFN package keeps the PCB design and manufacturing efforts at the min cost.
  • Ideal for monitoring high power amplifiers and adjust the parameters remotely.
  • Perfect for impairment measurements performed in CMTS and headend equiopments.
  • Works independent from Intel Puma processor, saving a lot of cost and power from the end application.
