"The protocol itself is kind of complex," said Vallier. "We use the packets themselves to clock each end of the signal because we can't have jitter. We can't have someone hearing a crack."Link Discuss (via /.!)
The current incarnation of the hardware is based on a custom media-access controller developed by Vallier and running on an Analog Devices Sharc DSP working with an FPGA designed by Schmidt and standard 100-Mbit/s Ethernet PHY chips. A separate analog board, designed by Gibson's Mike Dibble, uses multichannel preamps and four-channel A/D converters with integrated op amps.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
