Samsung Announces First 65nm ATSC Digital TV Receiver Chip


Samsung today announced an improved digital TV receiver chip, the S5H1411, that boasts a 30 percent higher reception success rate than the company?s previous generation digital TV receiver chip.

The chip enables digital TVs designed for the North American market to receive both vestigial sideband (VSB)* broadcasts and quadrature amplitude modulation (QAM)* cable signals.

Samsung's development of a high-performance digital TV receiver chip is expected to accelerate the expansion of the digital broadcasting base and household adoption of digital TV in North America.

The S5H1411 offers a higher reception success rate than other devices in multi-path environments where signal interference is high, such as densely populated urban areas; dynamic environments with serious signal distortion among many moving vehicles; environments with major signal phase errors because of cable retransmission and remote areas where reception is generally poor. Samsung is the first company to adopt 65nm process technology to broadcast TV receiver chip circuitry.

Moreover, the S5H1411 operates on 20 percent less power than competing devices on the market today, making it well suited for portable products such as the USB Dongle or USB box.

The new S5H1411 digital TV receiver chip is available in the 100-pin thin quad flat pack (14mm x 14mm) or 100-ball fine-pitch ball grid array (8mm x 8mm) packages. The footprint on the print circuit board can be reduced by as much as 40 percent. In addition to digital TVs, the device can be used in digital broadcast set-top boxes with terrestrial and cable reception, TV reception cards for PCs, USB Dongles and USB boxes.



*Vestigial Sideband (VSB) is the digital TV transmission standard for terrestrial broadcasts in the US, Korea, Canada and elsewhere. Frequency band utilization is high, and the format maximizes area coverage. Quadrature Amplitude Modulation (QAM) is a modulation method for cable broadcast reception is classified into technologies ranging from 4-QAM to 256-QAM, depending on the volume of data being transmitted. The 64-QAM form transmits data at 26.97Mbps.
