Oki Electric has enhanced its uPLAT series of integrated platforms, which lower development times of SoC LSIs, with the introduction of three core products.
More power from laser modules for WDM systems
Oki Electric has developed a trio of high-power 1480nm pump laser diode modules for WDM (wavelength division multiplexing) optical transmission.
"We made it very easy to embed a real time clock onto an equipment, as this small, high function module embeds all the functions necessary for a radio-controlled clock onto a single module", said Hiroyuki Hirata, President of Nagano Oki.
"We believe network home appliance manufacturers can utilise this module, as time stamps used in network home appliances are important for e-commerce in an advanced information telecom society".
Although there have been demands to embed radio-controlled clocks with auto adjustment function into equipment, it has been difficult because there were issues in developing software to convert the longwave standard to wireless technology and time information.
The NRC01 Series includes the ML6191, Oki Electric's single-chip LSI for radio-controlled clocks with the software, the antenna and a crystal resonator onto a single module.
Because all the peripheral circuits necessary to enable a radio-controlled clock are mounted onto a single module, radio-controlled clock functions can easily be embedded into equipment by simply connecting the module to the host micro controller.
Nagano Oki provides two types of modules: the standard type with the antenna in the module, and the antenna separated type with the antenna and mobile separated with a flexible cable.
The antenna separated type can improve its receiver sensitivity by changing the direction or settings of the antenna.
The reception can be improved further by combining with other large antennas.
Nagano Oki has begun sample shipments of the module, and will start volume shipment from April to the Japanese market.
The company also plans to develop modules for other wavelengths for international applications.
