mirics SDR USB Dongle FlexiTV MSi3101SDR USB Dongle FlexiTV™ MSi3101

MSi3101 – RF-to-USB Front-end

The MSi3101 silicon front-end, when paired with a software demodulator, enables broadcast TV, radio and GPS reception targeting processor-based platforms such as notebook computers. The MSi3101 comprises Mirics’ proven multi-band FlexiRF™ tuner (MSiooi), and Mirics’ USB interface chip (MSiasoo). The FlexiRF tuner enables low-power multi-standard broadcast reception, whilst the USB interface chip simplifies interfacing to a host processor by integrating standard USB2.o connectivity. Optimized for Mirics’ FlexiTV™ platform, the MSi3101 is also ideal for broadcast receiver applications using 3rd party software demodulation.

PC Requirements

The host computer must meet the following requirements

  • Operating System: Windows Vista 32bit/64bit
  • Intel dual core processor, e.g. Core2Duo 2.0 GHz or higher
  • High Speed USB 2.0 port

Performance Recommendations

For the optimum viewing experience and enhanced multi-tasking we would recommend a processor faster than the minimum stated above. Other factors such as the power management settings may reduce the available CPU processing power leading to a poor user experience with some DVB-T signals. As such it is recommended that the “Power Options” (available through the Control Panel) are set to “High Performance” mode.
