[net.ham-radio.packet] Dual Channel NRZI Encoder/Decoder

Universal Semiconductor Inc. has announced their USC SL2002 Dual Channel NRZI
Encoder/Decoder chip.  It is CMOS, in a 22-pin standard DIP, and all inputs
and outputs are TTL compatible.  Each of the 2 channels converts NRZ TX data
into NRZI, and also converts incoming NRZI into NRZ; it would seem to be the
perfect chip to mate with, say, the Zilog SIO for use in packet applications.
It replaces the need for the state machine which is now used on many designs.
The chip runs on +5v at 100 uA max quiescent current.  It handles 2 Megabits
per second.

N.B.: I have not used this device.  I am reciting data from the spec sheet.
Delivery is from stock.  Small quantity pricing is $50, but this price should
drop as production ramps up.
