Broadcom WLAN chips cut 802.11n router costs

Taipei, Taiwan—Broadcom Corp. announced three WLAN router products with integrated processors that will enable a full line of 802.11n routers with high performance and consumer-friendly cost points.

Wi-Fi manufacturers can use the latest Intensi-fi XLR products, which include the BCM4716, BCM4717 and BCM4718, to build simultaneous dual-band routers for high definition (HD) video streaming. They can also leverage its silicon integration to reduce the cost difference between 802.11n and 802.11g products.

To provide a strong wireless backbone for the networked home, Broadcom has optimized its new 802.11n router platform with Accelerange technology—a set of hardware and software enhancements that ensures more robust wireless coverage in the far corners of a home.

The BCM4716, BCM4717 and BCM4718 WLAN provide Wi-Fi vendors with a single platform to build single-band and dual-band 802.11n routers with distinct feature sets and price points. Each of the chips combines most of the elements needed to build a 2-stream 802.11n router([i]), including a MIPS 74K processor, onto a single monolithic die.

Broadcom's highly integrated 65-nm designs reduce the number of system components, which lowers the rest of bill of materials (RBOM) cost by up to 35 percent. The products further reduce cost by using two-layer PCBs, making high-end routers more affordable to consumers and bringing the price of basic 802.11n routers within the range of 802.11g products.

Broadcom's dual-band products offer a small footprint and on-board processor that make it easier for manufacturers to build compact Wi-Fi access points and travel routers, or add dual-band 802.11n capabilities to consumer electronics, such as digital televisions, set-top boxes and other video equipment.

Pricing: For low-volume quantities, the BCM4716 starts at $13.50; BCM4717 at $15.50; BCM4718 at $19.00; and BCM4323 at $9.50.
Availability: Sampling to early access customers with production quantities expected to ship in the third quarter of 2008.
Datasheets: BCM4716, BCM4717 and BCM4718.
