Kindness semiconductor Pu introduce the high-performance silicon tuner TDA18274 intelligently
Intelligent Pu semi-conductive NXP Semiconductors N.V of kindness. Claim to introduce a breakthrough high-performance silicon tuner TDA18274 recently, can be used in global ground and cable TV to receive. TDA18274 hybrid silicon tuner supports all simulation and digital television standard, two kinds of editions can be used: One kind adopts 48 pins HLQFN to encapsulate, directs against the direct ” board year ” The type is designed and optimized, the totally integrated radio frequency wave filter; Another kind adopts 40 pins HVQFN to encapsulate, carries the wave filter of external UHF and VHF. TDA18274 employs and optimizes to many tuners at the same time, integrated radio frequency frequency division device function, have avoided the demand for the auxiliary chip, and can realize the sharing of 16 – MHz crystal singly through shaking and exporting the bumper brilliantly, offer one the intersection of control and interface, rely on four the intersection of I2C and address but management.
TDA18274 also has a strong LTE ability to resist interference – -Spread out with using fast in the world for the ultra quick LTE network of the analogue TV frequency band, and the constant popularization in consumers of 4G LTE cell-phone, LTE interferes with already becoming a great difficult problem of perplexing the TV industry. TDA18274 improve to some extent in treatment that DTG D-Book 7 requires still, and to other and stray electromagnetic to interfere with EMI A interference inclusive has strong immunity. Kindness Pu world consumed the electronic exhibition in 2012 in Las Vegas such as state such as Nevada intelligently CES Show TDA18274 location number of exhibition: Central Plaza 8 .
Incident / focal point
The other functions of TDA18274 high-performance silicon TV tuner include:
The radio frequency inputs the bandwidth to expand to 1 GHz, accord with OCUR norm to upgrade
It is 3 to 7.5 MHz, very compatible with SoC height that flexible low intermediate frequency outputs interface frequency range
Similar best phase place noise performance; The return waves echo losses and is higher than 8 dB, the noise coefficient is 4 dB
Two common outputs GPO Pin
Do not need outside LNA, SAW wave filter and extra one in the choke of mould altogether, does not need to adjust manually either
The cost of supplies is lower, less than 0.30 dollars, including eBoM, connector and shield
Offer 48 pins 7-mm x 7-mm With 40 pins 6-mm x 6-mm Two kinds of encapsulation of HL/HVQFN
TDA18274 accords with the following standards:
All simulation in the global range PAL, SECAM, NTSC With digital television standard DVB-T/T2, DVB-C/C2, ATSC, ISDB-T, DTMB, J.83B
ARIB STD-B21 Japan, Brazil , A74-2010 U.S.A. , C-Book European Union , D-Book 7 Britain , E-Book European Union , CENELEC EN55020 European Union , NorDig 2.2 European Union With OCUR U.S.A. Wait for the norm
Appraise actively
Gerry Kaufhold, analyst of In-Stat, say ” kindness Pu have the intersection of trade and leading abundant experience in the field of silicon tuner intelligently, support all worldwide radio standards in an all-round way, and special radio frequency preparation method and strong the whole world supply the chain, this is one of manufacturers’ key considerations of a television, because what they valued is high performance and high dependability. Rely on latest the intersection of style and hybrid the intersection of silicon and tuner, kindness Pu promote from traditional pot tuner to the intersection of ‘ year such as board ‘ and the intersection of silicon and the intersection of TV and great transition of tuner intelligently. The tuner size of silicon is smaller, dependability is higher, the consumption is lower, therefore the cost-effective advantage is more outstanding. ”
Kindness semi-conductive the intersection of TV and the intersection of front and the intersection of product line and international Fabrice Punch, manager of product market, Pu say intelligently: “A lot of customers of ours have already begun to sell and carry the television of the silicon tuner chip in year of the board. We introduce the purpose of TDA18274 for board year the silicon tuner is approved by the masses in larger range. TDA18274 incorporates numerous advantages into an organic whole, include the ability that highly integrated design, many tuners of support employ and strong immunity interfered with to LTE and other wireless networks, it is TV manufacturers’ ideal choice, will help TV manufacturers to reduce the quantity of the essential assembly, nowadays give full play to silicon is tuned the utensil up advantages such as some simplicity, high performance, low supplies cost,etc.. ”
