Abstract
A configuration for routing electrical signals between a conventional electronic integrated circuit (IC) and an opto-electronic subassembly is formed as an array of signal paths carrying oppositely-signed signals on adjacent paths to lower the inductance associated with the connection between the IC and the opto-electronic subassembly. The array of signal paths can take the form of an array of wirebonds between the IC and the subassembly, an array of conductive traces formed on the opto-electronic subassembly, or both.
Claims6
An arrangement for providing a low inductance electrical connection between an electronic integrated circuit and an opto-electronic subassembly for communicating a complementary-encoded data signal therebetween, defined as a DATA signal component and a DATA signal component, the arrangement comprising
- an array of parallel signal paths disposed between the electronic integrated circuit and a predetermined location on the opto-electronic subassembly, the array including a first set of signal paths for carrying the DATA signal component;
- and
- a second set of signal paths for carrying the DATA signal component, wherein the signal paths forming the first set and the second set are interleaved such that oppositely-signed signals are carried on adjacent signal paths so as to create a low inductance within the array of parallel signal paths.
