With the resurgence of the consumer industry, TV manufacturers are actively seeking cutting-edge technologies to support all Chinese TV broadcast signals and various operational modes, while simultaneously lowering production costs and accelerating time-to-market. Moreover, the ultra-thin TVs showcased at this year’s CES are pushing semiconductor companies to develop more compact and lightweight devices.
Maitong has recently introduced a cost-effective DTV receiver chip solution tailored for the Chinese market. This solution integrates a tuner and a demodulator (Demod) into a single chip, offering high integration that can be used both domestically and internationally. By simplifying the front-end design of TVs, it helps reduce costs and improve reliability, enabling Chinese manufacturers to deliver superior terrestrial and cable TV reception across different sizes, models, and price points.
**Key Features: Integrated Modem**
The high-performance DTV receiver chip from Maitong includes the MT3141 multi-standard RF receiver chip and the new MT886x demodulator family. This chip solution is built on widely recognized technology and complies with China’s digital TV terrestrial transmission standard GB20600-2006 (CTTB/DTMB), exceeding the requirements set by the China Electronics Standardization Institute (CESI).
"Most competitors offer either a tuner or a demodulator," said Pete Birch, Director and Global DTV Business General Manager. "Our key breakthrough is integrating the tuner and analog TV demodulator into one device." The chipset is based on Maitong’s MT3141 receiver and includes one of four CTTB-compliant channel demodulators from the MT886x family. The patented FADE (Fading and Equalization) architecture ensures excellent performance, significantly improving end-user TV reception.
The MT3141 is a complete RF-to-baseband, single-chip, multi-standard tuner with an integrated PAL/SECAM/NTSC analog demodulator. It features exceptional sensitivity and strong adjacent-channel rejection. These technical advantages directly translate into improved DTV signal coverage and reception quality. The MT886x series minimizes the need for external components, with each product integrating memory that supports all CTTB operating modes in China and Hong Kong, making it a true system-on-a-chip. By embedding memory on the silicon, Maitong has reduced the bill of materials and shielded TV manufacturers from DRAM price fluctuations—something that often impacts vendors using SIP or MCM solutions.
"Combining the tuner and demodulator offers clear technological and cost benefits. Our customers have responded very positively to this solution," said Birch. "MT3141 is just the first in the series; we plan to release more national standard products in the future. We designed the series to be compatible globally, so manufacturers don’t need to differentiate between regions. This helps save on field and design costs, improves overall production control, and enhances design quality. Additionally, the MT3141 provides world-class receiver solutions for Chinese TV manufacturers aiming to expand into overseas markets."
**Target Application: Local Triple Play**
China is advancing its strategy to accelerate the integration of three networks. In response, Maitong’s latest MT3141 chip is well-prepared for this trend. First, it supports set-top box solutions with excellent QAM256 and QAM64 performance. Second, it integrates OOB (Out-of-Band) channel functions, including low-power amplifiers and filters specifically for this market. This makes the chip ideal for “triple play†digital interactive set-top boxes.
Traditionally, basic set-top boxes only required one tuner for receiving content. However, in the high-definition era, operators are looking to add value through services like video-on-demand or picture-in-picture, increasing the demand for two tuners. In the U.S., cable set-top boxes typically use silicon tuners, but in China, the market is still transitioning from CAN tuners to silicon tuners. This shift is expected to take about 8 months to 2 years.
Pete Birch also noted that many local manufacturers have their own modem solutions, which benefit from policy advantages, making it easier for them to promote in the domestic market. However, Maitong’s chips are developed, produced, and packaged in China, with sales and support also handled locally. While there may be some policy-related challenges, Birch remains confident in the chip’s high performance and cost efficiency.
"For the Chinese market, Maitong has developed two generations of digital TV chips, and this is our third-generation solution tailored for China’s digital TV standard. All products for the Chinese market are developed in China," he added.
