TAIPEI, Taiwan Home networking specialist Realtek Semiconductor Corp. is breaking into the nascent market for ultrawideband devices with a physical layer chip based on the WiMedia Alliance PHY specification.
Although a few Taiwanese companies have expressed interest in the UWB market, Realtek is the first design house here to announce a chip for the emerging technology, which is alternately viewed as a competitor and complement to IEEE 802.11x technology. The standard calls for data rates at up to 480 Mbps across short distances, typically about 10 meters.
Realtek’s RTL8170 supports Transmit Power Control and Link Quality Indication, making it suitable for immediate use in combination with MAC solutions implementing Certified Wireless USB (from the USB-IF), and WiNET (IP over UWB), the company said.
The RTL8170 comes with a reference design providing support from MAC-PHY interface to antenna. Including external components, the overall footprint is 12 mm x 12 mm. Samples will ship in the fourth quarter.
