IceFyre aims at 802.11a, a/b/g chipset market

Wireless chipset company IceFyre Semiconductor today released details of its TwinFyre 802.11a/b/g chipsets .

The company said the chipsets’ 802.11a specs feature 1W output power at 54 Mbit/s (megabits per second), and 10 dB better receive sensitivity and 2 dB better transmit signal linearity (EVM) than competing products.

The TwinFyre chipset’s 802.11b/g specs include -30 dB EVM in 802.11b and -27 dB EVM in 802.11g operation respectively and over 20 dBm average RF output power.

Both products have an ultra-low power Media Access Controller (MAC) that has block-by-block power control of the physical layer. IcFyre claims 50 percent reduction in peak transmit power consumption, 20 percent less receive power and 5 mW in sleep mode.

The SureFyre 802.11a chipset is comprised of the ICE5125 MAC, ICE5351 5GHz OFDM PHY and ICE5352 5GHz OFDM PA. The TwinFyre 802.11a/b/g system has the same MAC and PA chips, but adds an ICE5825 Dual-band PHY and ICE2501 802.11b/g radio.

The ICE5125, ICE5351 and ICE5352 are sampling to customers now with SureFyre-based Mini-PCI reference designs available in Q4 2003 . Volume production of the SureFyre 802.11a chipset will begin in Q1 2004 . The TwinFyre 802.11a/b/g chipset will begin sampling to customers in Q2 2004 with volume production scheduled to commence in Q3 2004 .
