SN65LVDS100: Conversion of LVDS to RS-422 for high speed signals

Part Number: SN65LVDS100

Tool/software:

Hello.  Conversion of LVDS to RS-422 is easy enough to accomplish.  A typical LVDS receiver can convert to a TTL level.  This signal can then drive a RS-422 driver.   But I'm looking for a circuit that can go directly from LVDS to RS-422 without the intermediate conversion to a non-differential, intermediate signal.   So far, I have not seen any example circuits to accomplish this but Pulse Research does seem to offer an expensive device that at at least appears to do a direct conversion.   Can anyone point me to a solution?  Thanks.
