serial SECL to DECL conversion

[kkoorndyk]

Hello,

I need to convert from a serial single-ended ECL signal to serial differential ECL. I'm using a SyntheSys BitAlyzer 1000. This unit has serial SECL I/O with SMA and BNC connectors. I need to interface to an Agilent Optical Transceiver which is expecting Differential inputs. So, I'm looking for a SECL to DECL converter. My internet searches have all come up with SCSI converters, but since both the BitAlyzer and the Agilent transceiver have SMA connectors I'd rather not mess around with parallel differential signals and a SERDES. Does anyone have any suggestions?

Thanks.

I'm confused, what does SCSI have to do with ECL?

Also, why not simply use an ECL buffer?

If you don't have too much noise, you can use a decoupled
ref. voltage on one end of the diff. input or do the same
with a line receiver/buffer close to the SE source.
