Product Brief MT3141 MT3141 World-Standard Receiver The MT3141 MT3141, based on the MicroCeiverTM architecture, is a single chip receiver that integrates all the functions of the RF tuner, analog demodulator, IF filters, and amplifiers in a single IC. Related Product Information: Press Release Related Products Order Information Cable Product Selector Guide Description The MT3141 MT3141 receiver is a world-standard solution designed to ease implementation of highperformance terrestrial and Tru2WayTM television receivers. It also supports advanced analog/digital set-top boxes (STB) and home gateway applications. The MT3141 MT3141 was designed to deliver the best performance both in off air terrestrial and cable reception. The IC needs only a relatively simple bill of materials to make the required small PCB footprint for slimmer flat panel TVs. No balun or SAW filters are required. Applications Integrated Digital TV sets for terrestrial and cable reception Tru2Way iDTVs Hybrid (analog/digital) STBs and DVRs/PVRs Hybrid (analog/digital) home gateway applications Hybrid (analog/digital) PCTV applications Analog/Digital terrestrial or Tru2way cable DVR Analog/Digital ½ NIM, ¾ NIM or full NIMs Features NTSC/PAL/SECAM synchronous demodulation with active carrier regeneration with composite video (CVBS) and sound intermediate frequency (SIF) outputs Flexible standard or low IF output that supports nearly all digital demodulators available Low external bill of materials: No balun, SAW filters or active components required.
