    New Product
    March 12, 2009, Osaka, Japan—Panasonic Electronic Devices Co., Ltd. has succeeded in commercializing the in-vehicle terrestrial digital front-end unit with 4-diversity reception (TTM15J type), which futures excellent receiving performance under the hard automotive environmental conditions.
    Product name In-vehicle terrestrial digital front-end unit with 4-diversity reception
    Type name TTM15J
    Model number ENA94J ** C3F
    Sample price 15,000 yen /unit
    Production start April 2009
    Production capacity 50,000 units/month
    Since the terrestrial broadcasting /receiving system in in-vehicle TV and automotive navigation systems will be completely digitized from the year of 2011, a digital receiving front end built in vehicles has come into wider use. And also, 4-diversity reception systems have been increasingly required to have the higher-sensitive receiving performance in the market. To meet the market demand, Panasonic Electronic Devices Co., Ltd. has succeeded in single-packaging (currently in 2-packaging) 4-diversity function and commercialized the TTM15 type, which has a smaller size, lower power consumption as well as higher sensitivity.
    [Features]

    1.Single-packaging 4-diversity receiving performance, contributing to downsizing devices

    Mounting area: 20 cm2   Approx. 55 % reduction compared with our current
    models (*1)

    2.Low power consumption, contributing to saving power and improving reliability of devices

    Power consumption: 2.4W   Approx. 15% reduction compared with our current
    models (*1)
        2.5 W at 2TS transport stream

    3.Improvement in receiving performance at high-speed driving and the wide
       dynamic range, contributing to broadening the receiving area

    Sensitivity at high-speed driving: min. 200 km/h (*2)
    Wide dynamic range: capable of receiving from strong electric field (＋10 dBm) just under the transmission tower to weak radio waves of one-segment (-100 dBm @ 5.57 MHzBW)

    4.2TS (transport stream) output available, improving the 2-screen function

    TS output: 1 TS available, 2 TS available (option)
                                                              Our current models (*1): 2TS not available
    (*1) Our current models: 4-diversity terrestrial digital front-end (consisting of TTM8J type and ET-08DHR type)
    (*2) TU-6 simulation value at laboratory (when Rayleigh fading property is in accordance with TU-6 regulations)
    The value of 200 km/h means that pictures are not disordered at the speed of 200 km/h.
    [Applications]
    In-vehicle terrestrial digital tuners, Automotive navigation systems, Rear entertainment systems
