11/5/2004 - Cypress Semiconductor Corp. (NYSE: CY) announced that its industry-leading HOTLink IITM physical layer (PHY) family meets the Common Public Radio Interface (CPRI) specification version 1.2. CPRI focuses on a 3G radio basestation design that divides the radio basestation into a radio and a control part, by specifying one new interface - the only and unique radio driven interconnect point within basestations. This will enable each part of the basestation to better benefit from the technology evolution in its respective area.
The CPRI specification is openly available for the benefit of the wireless industry. Key benefits for Network Operators are the availability of wider radio basestation portfolios providing adaptability to all deployment scenarios with a shorter time to market. The CPRI specification enables basestation manufacturers and component vendors to focus their research and development efforts on their core competencies and also allows for new architectures not limited by module dimensions or a pre-defined function split.
“The CPRI spec defines a single, standardized interface between the digital components of a basestation and the RF segment, thus creating cost-reduction and faster time to market opportunities at one of the most critical serial links of a system,” said Erin Kettwig, product manager for Cypress’s Data Communications Division. “By using Cypress’s HOTLink II family of PHYs, system vendors are guaranteed a simplified integration with hardware developed independently on either side of the interface.”
Cypress is a long-time supplier of backplane PHY transceivers that enable the transport of data over high-speed serial links (optical fiber, balanced and unbalanced copper transmission lines, and board traces). The HOTLink II family of PHY devices supports serial data rates of 614.4 Mbps and 1228.8 Mbps on any channel within a single chip. The chips also include a multi-byte framer for more robust framing in CDMA, W-CDMA and GSM/EDGE applications, and support selectable Comma (K28.5) character framing options between both message groups and master frames. Cypress’s HOTLink II devices all feature low jitter, 8B/10B ENDEC capabilities, and are available in single-, dual-, quad-, and independent-channel configurations.
The HOTLink IITM family of CPRI-compliant physical layers is available now.
