Product details

Audio codec for telecom line cards

The PSB2161TV1.1 is an ARCOFI-SP audio ringing codec from Infineon, classified as Type Audio in the Sensors & Transducers category. It integrates one ADC and one DAC with a serial data interface, purpose-built for generating and processing ringing tones in telecom line cards and subscriber-line interface circuits. Operating from a single 5V rail — both analog and digital supplies share the 4.75V to 5.25V range — which keeps the power tree simple: one 5V regulator feeds the whole device.

Temperature range and package fit

Rated for -25°C to 80°C, this part suits outdoor telecom cabinets and factory-floor PBX equipment where the ambient stays above freezing but does not reach the full industrial 85°C ceiling. The 28-SOIC (7.50 mm width) body in P-DSO-28 footprint is a standard surface-mount package — no exotic reflow profile needed.

Active production — no obsolescence watch

Infineon lists the PSB2161TV1.1 as Active.

Frequently asked questions

What supply voltage does the PSB2161TV1.1 require?

Both the analog and digital supply rails accept 4.75V to 5.25V. A single 5V ±5% regulator covers both domains — no separate 3.3V or 1.8V rail needed.
