optical receiver for 850nm (PD + TIA + LIA + LVDS output)

16/11/2007 - 12:16 von Toni M. | Report spam
Hi fellow engineers,

I am designing an FPGA board and I want to include an optoelectronic
interface on the board. What I have in mind is a 1-channel optical receiver
module (digital data output), packaged for integrating directly on-board
that features the photodiode (SiGe or any III-V metarial), all amplifiers
and a differential line driver, like LVDS or LVPECL for connection to the
FPGA. The envisioned data rate is something between some MHz and max. 1 GHz,
but it does not play a major role.

I already searched the internet for days now but all I found were some
parallel optical receivers (like Infineon's PAROLI which is already
obsolete) or complex multi-channel transceivers that are sort of overkill
for my application. Aren't there any plain 1-channel optical receivers
available on the market? Unfortunately it's hard for me to get a
substantiated overview because I never had to deal with optics and photonic
components before.

Thank you all very much in advance!

Toni

A3PICs has developed a 850nm-Version of its ARX30125 receiver, a chip
that contains a complete 1.25Gb/s optical receiver (PD, TIA,
LVDS-driver): http://a3pics.com/newproducts.htm
Usually, they sell unpackaged chips, but you didn't say what kind of
package or what quantities you wanted to have...

Regards,
Michael.
