Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
The MSC1210 family integrates a 24bit delta-sigma analogue-to-digital convertor (ADC) with an enhanced 8051 processor core, Flash memory and a variety of high-performance on-chip peripherals to achieve unparalleled system performance - all at 4mW power consumption.
The integration of the analogue and digital cores gives customers the ability to customise the device to meet their specific requirements.
It would be much more costly and difficult to achieve the same level of flexibility and performance using multiple devices.

Advanced TDMA technology to boost cable bandwidth
Texas Instruments has unveiled its new technology featuring end-to-end advanced TDMA that will enable a 50% increase in upstream plant capacity.
The enhanced 8051 core executes up to three times faster, with lower power, than the standard 8051 core.
The MSC1210 family offers a variety of flash memory sizes with pin and function compatibility, thus allowing the customer to freely migrate between devices as their code requirements change.
In terms of analogue performance, the MSC1210 family offers the industry's lowest noise performance in a mixed-signal device (75nV).
Furthermore, the ADC on the MSC1210 family has a much faster sampling rate than comparable devices.
"Providing an unsurpassed level of high-performance functionality in a single chip, which was traditionally implemented with external circuitry, has positioned the MSC1210 family as the most valuable data conversion system on the market.
This device will simplify the design of complex systems and reduce overall component cost", said Robert Schreiber, product line manager for TI's data acquisition system products.
"The noise performance of the ADC is better than most stand-alone ADCs on the market and is significantly better than any comparable mixed-signal device.
The enhanced 8051 core, along with the high-performance peripherals, pushes the performance envelope of the digital processing while maintaining analogue signal integrity".
The analogue features of the MSC1210 family consist of a 24bit delta sigma ADC, a flexible eight-channel multiplexer, burn-out current sources, selectable buffered input, offset digital-to-analogue convertor (DAC), programmable gains of up to 128, selectable data output rate, programmable single-cycle settling filter, precision on-chip voltage reference or external differential voltage reference, on-chip temperature sensor, on-chip calibration, low voltage detect and brown-out reset.
The digital features of the MSC1210 family include an enhanced 8051 microcontroller core with dual data pointers, four Flash memory size options (4K, 8K, 16K, 32K) - all with external memory capability as well - 1.2Kbyte of SRAM, 34 I/O lines, an additional 32bit accumulator/shifter, dual UARTs, three timers/counters, SPI interface with direct memory access and a watchdog timer.
The four different sizes of flash memory allow the customer to optimise the memory size to their application and provide an easy migration path to larger memory sizes without having to add external memory, as required in other devices.
The MSC1210 family is packaged in a TQFP-64 and operates on a single 2.7 to 5.25V supply.
