Demodulator cuts terrestrial boxes down
to size
A new orthogonal frequency division multiplexing demodulation LSI enables compact and low-price set-top boxes with high quality reception of European digital terrestrial broadcasts.
NEC Electronics has developed an orthogonal frequency division multiplexing (OFDM) demodulation LSI for compact and low-price set-top boxes (STBs) with high quality reception of European digital terrestrial broadcasts Sample shipping of the uPD61540 will begin in October 2005

Cutting the cost of hi-rel satellite devices
NEC's low-earth orbit L-Grade high-reliability devices include transistors and monolithic microwave ICs (MMICs) in both silicon and gallium arsenide (GaAs) technologies.
1Mbit SRAM retains its data at low voltages
NEC's latest 1Mbit SRAM is designed using full CMOS process memory allowing it to operate with supply currents as low as 25mA and with supply voltage 1.8-3.6V.
The uPD61540 is designed for use between the tuner and the MPEG decoder LSI, and has every function required to demodulate transmissions from terrestrial television broaDCast received by the tuner, to a transport stream (TS) which can be processed by an MPEG decoder LSI.
It has an integrated digital IF filter, eliminating the need for switched bandwidth surface acoustic wave (SAW) filters in the tuner design, reducing the size and cost of the STB.
It is optimised to perform at high levels even in the harshest environments, with a built-in recovery circuit that eliminates delayed or reflected signals, and is compliant with the stringent NorDig Unified 1.0.2 standard.
Combining the uPD61540 with a suitable LSI which converts TS data to audio/video signals, such as NEC Electronics' uPD61110 MPEG decoder, enables the affordable and speedy development of STBs that receive European digital terrestrial broadcasts, or advanced tuners with OFDM functions, which require smaller footprints and must perform in harsh environments.
Since the first launch in the UK in 1998, terrestrial digital broadcasting has spread to other countries in Europe, but reception of these broadcasts demands higher performance from OFDM-based devices to help avoid data errors due to reflective waves, especially in mountainous regions.
In addition to this higher performance, the STBs and tuners must also meet cost and space requirements.
NEC Electronics has introduced the uPD61540 to answer this market demand, support the spread of terrestrial digital broadcasts in Europe, and will continue to offer solutions for digital television, DVD recorders, STBs and other applications with LSIs based on NEC Electronics' EMMArchitecture.
Samples of the uPD61540 will be available in October 2005.
Volume production will start in February 2006, and production is expected to reach 500,000 units per month.
Availability is subject to change.
