Single-chip QPSK tuner
cuts component counts
Fujitsu has developed a single-chip solution it reckons is an attractive alternative to discrete QPSK NIM modules
The MB86A15 integrates a zero IF tuner, a QPSK demodulator and forward error correction (FEC) circuitry ideal for DVB-S and DSS transmissions, as well as tuning-diodes, capacitance and inductive elements. Therefore only a few external components are necessary to complete a design. In addition, the MB86A15 internally generates the control signal for DiSEqC 1.x, which reduces the amount of software needed.

Mapper manages Ethernet LAN/WAN transport
With support for multiple mapping modes, the device provides maximum flexibility to manage Ethernet LAN/WAN transport over metro and core networks
Memory chip handles four lines of HDMI
Single embedded FRAM chip provides display data memory for four HDMI connector ports, which previously required separate memory for each port
The device operates from supply voltages of just 2.5, 3.3 and 5V.
Due to the extremely low power consumption with a maximum dissipation of 1.5W (45Mbaud), it is available in a compact LQFP 120-pin package.
The evaluation kit for the device includes the LNB supply and also 22kHz modulation circuitry.
Fujitsu provides end users with the application programming interface software in source code free of charge.
Through the use of Windows based monitoring software, the evaluation and development processes are significantly simplified.
For example the Windows software offers the user a graphical bit error rate display, bargraphs for signal strength and quality, and transponder administration using the DiSEqC standard.
