NewLogic Technologies has developed a WLAN dual-band radio IP core in CMOS technology with a digital interface (Hiss).
The Hiss interface is a low-pin-count digital link between radio and baseband chips replacing the analogue I/Q interface.
The advantage of such a digital interface is that analogue functions, like A/D and D/A convertors are all moved into the radio.
Therefore the baseband chip does not need to contain any WLAN-related mixed-signal blocks, which reduces the SoC design effort, improves yield, reduces the test effort and allows the design to be ported to different technologies without having to redesign the process-sensitive data convertors.
The basis for this new member of the NewLogic radio IP is the Wild radio: a 2.4 and 5GHz dual-band 802.11 a/b/g WLAN CMOS radio macro usable for stand-alone solutions or for integration with standard WLAN ICs and ASICs.
