Highly integrated silicon tuner helps design ultra-thin flat-screen TVs
With the rapid development of cable, satellite, terrestrial broadcasting and Internet content transmission technologies, televisions and set-top boxes have entered a new digital era. Silicon tuners are gradually replacing old radio-frequency analog circuits, and highly integrated, compact tuners have a huge demand. NXP Semiconductors' high-performance silicon tuner TDA18272, for global wireless and cable TV reception applications, supports PAL, SECAM, NTSC analog TV standards and DVB-T / C, DVB-T2, ATSC, ISDB-T , DMB-T digital TV standard, allowing TV manufacturers to prepare for the next generation of TV.
Since silicon tuners are about to replace various traditional CAN tuners based on MoPLL, TDA18272 meets the increasing global demand for highly integrated low-power ultra-thin TV architectures. The small size of the TDA18272 uses a 40-pin, 6x6 mm package, which contributes to the design of ultra-thin flat-screen TV panels. TDA18272 is highly integrated, with RF tracking filter, oscillator, IF selection module and broadband gain control module, without external components such as SAW filter and balance converter. NXP uses TDA18272 to introduce a unique master / slave architecture designed to optimize the multi-tuner application architecture.
TDA18272 provides TDA8296 IF demodulator as an auxiliary chip for global analog TV demodulation. The IF demodulator integrates a programmable group delay function and a video gain equalizer to optimize system design. In order to shorten the time to market, NXP also provides a full set of auxiliary design kits (circuit boards, documents and software packages) for testing and evaluation.
The main features of TDA18272 include: 3.3V single supply voltage; 40-pin small size HVQFN package (6x6 mm), ROHS compliant; no external low noise amplifier (LNA) and SAW filter required; master-slave version simplifies multi-tuner applications ; Integrated RF tracking filter, and fully integrated oscillator (no additional oscillator, IF selection module, low noise amplifier or SAW filter); fully integrated IF selection module; ROHS-compliant low-power green solution; integrated broadband Gain control; low phase noise; equipped with crystal output buffer (16MHz) for single crystal applications; I2C bus interface (3.3V / 5V); easy to program and can be adjusted at will; low IF output of 3-5MHz.
