Santa Clara, Calif. The IXF1110 Gigabit Ethernet and IXF1010 100/1000 Ethernet MACs are equipped with a SPI 4.2 interface. Unlike traditional SPI 4.2 interfaces, which are static, the new MAC devices include a dynamic-phase alignment version of SPI 4.2. Under the static approach, bits coming across the 16-b parallel SPI 4.2 bus are sampled at the same instant. In the dynamic approach, on the other hand, the bits are sampled separately, allowing a degree of tolerance to bits that are out of alignment. According to Intel, this allows the bus to better handle skew and jitter as data rates increase.
The IXF1110 is a 10-port Gigabit device for optical applications. This device integrates a serializer/deserializer (serdes) and an optics controller. The IXF1010, on the other hand, is a 10-port 100/Gigabit device for twisted-par network solutions.
Pricing: In 1000-unit quantities, the IXF1110 is priced at $245 while the IXF1010 is offer at $205.
Availability: Generally available in June
