TP3404 General Description

The TP3404 is a combination 4-line transceiver for voice and data transmission on twisted pair subscriber loops, typically in PBX line card applications. It is a companion device to the TP3401/2/3 DASL single-channel transceivers. In addition to 4 independent transceivers, a time-slot assignment circuit is included to support interfacing to the system backplane.

Each QDASL line 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.

Full-duplex transmission at 144 kb/s is achieved on single twisted wire pairs using a burst-mode technique (Time Compression Multiplexed). All timing sequences necessary for loop activation and de-activation are generated on-chip.

Alternate Mark Inversion (AMI) line coding is used to ensure low error rates in the presence of noise with lower emi radiation than other codes such as Biphase (Manchester). On #24 AWG cable the range is at least 1.8 km (6k ft.).

Reliability Metrics

Part Number	Process	EFR Reject	EFR Sample Size	PPM	LTA Rejects	LTA Device Hours	FITS	MTTF (Hours)
TP3404V	CS100	1	13986	72	0	898000	4	254809951

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.

TP3406 General Description

The TP3406 is a complete monolithic transceiver for data ransmission on twisted pair subscriber loops. It is built on ational's double poly microCMOS process, and requires nly a single +5Volt supply. Alternate Mark Inversion (AMI) ine coding, in which binary `1's are alternately transmitted s a positive pulse then a negative pulse, is used to ensure ow error rates in the presence of noise with lower emi radiation han other codes such as Bi-phase (Manchester).

Full-duplex transmission at 144 kb/s is achieved on a single wisted wire pair using a burst-mode technique (Time Compression ultiplexed). Thus the device operates as an ISDN U' Interface for short loop applications, typically in a PBX nvironment, providing transmission for 2 B channels and 1 channel. On 24 cable, the range is up to 800 meters.

System timing is based on a Master/Slave configuration, ith the line card end being the Master which controls loop iming and synchronisation. All timing sequences necessary or 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.
