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 +5 Volt supply. Alternate Mark Inversion (AMI) 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 radiation 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 Compression 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 #24 cable, the range is up to 800 meters.

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 programmed via the Microwire Control Interface.

A 2.048 MHz clock, which may be synchronized to the system clock, controls all transmission-related timing functions.

Reliability Metrics


Part Number Process EFR Reject EFR Sample Size PPM LTA Rejects LTA Device Hours FITS MTTF (Hours)

TP3406VCS0800305350028105002797458048

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
