TP3406
DASL Digital Adapter for Subscriber Loops
General Description
The TP3406 is a complete monolithic transceiver for data
transmission on twisted pair subscriber loops It is built on
National’s double poly microCMOS process and requires
only a single
line coding in which binary ‘1’s are alternately transmitted
as a positive pulse then a negative pulse is used to ensure
low error rates in the presence of noise with lower emi radia-
tion than other codes such as Bi-phase (Manchester)
Full-duplex transmission at 144 kb s is achieved on a single
twisted wire pair using a burst-mode technique (Time Com-
pression Multiplexed) Thus the device operates as an ISDN
‘U’ Interface for short loop applications typically in a PBX
environment providing transmission for 2 B channels and 1
D channel On
System timing is based on a Master Slave configuration
with the line card end being the Master which controls loop
timing and synchronisation All timing sequences necessary
for loop activation and de-activation are generated on-chip
Selection of Master and Slave mode operation is pro-
grammed via the Microwire Control Interface
A 2 048 MHz clock which may be synchronized to the sys-
tem clock controls all transmission-related timing functions
