Product details

The DS2148T+ is a single-channel Line Interface Unit (LIU) for telecom interfaces. It handles physical-layer encoding, jitter attenuation, and line driving/receiving for digital trunk lines. The 44-TQFP package keeps the board footprint compact for multi-port line cards.

Supply range and current — sizing the rail

The DS2148T+ operates from a 4.75 V to 5.25 V supply. Typical supply current is 95 mA.

Temperature grade — indoor telecom only

Not suitable for outdoor, industrial, or automotive applications without additional thermal management.

Frequently asked questions

What package does the DS2148T+ come in?

It is supplied in a 44-TQFP (10x10 mm) surface-mount package, shipped in trays.

Is DS2148T+ a direct replacement for DS2148?

The DS2148T+ is the tray-packaged variant of the DS2148 family. The 'T+' suffix typically indicates tray packaging; functional compatibility with the base DS2148 should be verified against the respective datasheets for pinout and electrical specifications.
