TP3420AV308 Description

Short technical summary and product information.

The TP3420AV308 from Texas Instruments is an enhanced ISDN S/T Interface Device (SID) designed for data transmission over twisted pair subscriber loops. Built on a 1.0-micron double-metal CMOS process, it requires a single +5V supply. This device provides full-duplex transmission at 192 kb/s using inverted Alternate Mark Inversion (AMI) line coding, supporting 2 "B" channels (64 kb/s each) and 1 "D" channel (16 kb/s), along with maintenance channels.

The TP3420AV308 supports various ISDN basic access configurations at the "S" and "T" interfaces, compliant with CCITT recommendation I.430 and ANSI T1.605. It can be configured as Terminal Equipment (TE), Network Termination (NT-1 or NT-2), or a PABX line-card/trunk-card device. The device features selectable TE or NT modes and exceeds the I.430 range with a 1.5 km point-to-point capability. An adaptive receiver ensures high noise immunity, making it suitable for premise wiring installations.

This transceiver is available in a 20-PLCC (9x9) package and is designed for surface mounting. It offers compatibility with MICROWIRE™ and SCP serial control interfaces and can interface with devices like the MC68302 processor and TP3054/7 Codec/Filter COMBO.
