Product details
Overview
PSB2163T-V31TR from Siemens is a single-chip ARCOFI®-SP audio ringing codec filter IC for digital telephones, integrating analog front end (AFE), programmable DTMF/tone/ringing generation, full-digital speakerphone with AGCX/AGCR, and IOM®-2 or serial control/data interface. It operates from +5 V, supports ETSI NET33 and CCITT G.714 standards, and delivers 16-bit linear PCM voice processing with on-chip loudspeaker amplifier and dual transducer correction filters.
For engineers reviewing the PSB2163T-V31TR datasheet, PSB2163T-V31TR pinout, PSB2163T-V31TR application, or PSB2163T-V31TR equivalent, this device is selected for ISDN voice terminals, PC-card voice/data adapters, multifunctional ISDN terminals, and digital fax/modem interfaces requiring integrated analog signal conditioning, real-time echo suppression, and programmable tone synthesis without external components.
Technical Context
The PSB2163T-V31TR implements a complete CCITT/ETSI-compliant voice processing chain: AFE with software-programmable gain stages (−12 dB to +36 dB per path), decimation/interpolation filters, and dual-path analog loopback test capability. Its ARCOFI® Signal Processor includes dedicated transmit/receive signal paths with programmable coefficient RAM for adaptive filtering and sidetone control.
It features two independent digital interfaces: IOM®-2 (TE/non-TE mode) supporting B- and D-channel framing plus MON channel monitoring, or SCI/SDI serial control with time-slot configuration. Tone generation uses a hardware control generator driving trapezoidal/sine/square waveforms at 8 kHz sampling rate with 3-dB-step square-wave ringing output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | +5 V ±5 % - single-supply operation enables direct integration into 5 V digital telephone systems without level-shifting. |
| Sampling Rate | 8 kHz - matches ISDN B-channel timing and ensures compliance with G.711/G.714 voice coding standards. |
| ADC/DAC Resolution | 16-bit linear PCM - provides ≥90 dB SNR for high-fidelity handset and loudspeaker audio paths. |
| Speakerphone AGC Range | AGCX: 0–30 dB gain control; AGCR: 0–24 dB - dynamically stabilizes near/far-end speech levels under varying acoustic conditions. |
| Tone Generation | DTMF (transmit/receive), trapezoid/sine/square waveforms - supports pulsed multi-tone call signals and ETSI-compliant ringing sequences. |
| Interface Modes | IOM®-2 (TE/non-TE) or Serial Control/Data (SCI/SDI) - enables flexible system integration with ISAC®-P layer-1 devices or microcontroller-based hosts. |
| Power-Down Current | <100 µA - allows battery-backed standby in cordless or portable digital telephone applications. |
Pinout & Package
PSB2163T-V31TR is housed in a P-DSO-28 (plastic dual small-outline) package with 300 mil body width, gull-wing leads, and standard JEDEC MS-013AC footprint. Thermal pad not present; lead finish is matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Power supply | +5 V main supply for analog/digital core; requires local 100 nF ceramic bypass. |
| GND | Ground reference | Analog and digital ground shared; layout separation recommended for noise immunity. |
| HON / HOP | Handset output/earpiece drive | Differential analog outputs for electro-acoustic transducers; gain programmable via ATCR/ARCR registers. |
| LSPK | Loudspeaker driver | Class-AB output capable of driving 8 Ω loads directly; supports square-wave ringing at 3-dB steps. |
| MICIN | Microphone input | Single-ended input with programmable gain (0–42 dB); includes bias voltage for electret mics. |
| DCLK / DDATA | Serial data clock/data | SDI-mode interface pins; support 1.544/2.048 MHz frame sync and time-slot multiplexing. |
| IOMD / IOMC | IOM®-2 data/clock | Asynchronous IOM®-2 interface pins; enable direct connection to ISAC®-P or SICOFI® line cards. |
| RESET | Active-low reset | Hardware initialization trigger; must be held low ≥100 ns after VDD stabilization. |
Key Features
| Feature | Design Value |
|---|---|
| Fully integrated speakerphone | Digital echo cancellation via programmable FIR coefficients, AGCX/AGCR, and loudhearing mode - eliminates need for external DSP or hybrid circuits. |
| Transducer correction filters | Two independent programmable FIR filters (TX/RX paths) - compensate frequency response mismatches of specific earpiece/loudspeaker models. |
| Multi-standard tone generation | DTMF (ITU-T Q.23), ETSI ringing (NET33), and custom trapezoidal/sine tones - all generated in real time without host CPU intervention. |
| Flexible analog front end | Software-configurable gain (−12 dB to +42 dB), high-pass disable control, and dual microphone inputs - supports both handset and handsfree operation. |
| Low-power standby | Power-down state draws <100 µA while retaining register contents - extends battery life in portable ISDN terminals. |
Applications
| ISDN Voice Terminal | PC-Card Voice/Data Adapter |

Equivalent & Alternatives
The following parts are listed as comparable options for similar audio ringing codec applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PSB2165T-V31TR | Two receive channels, LGA gain stage, programmable MON attenuation, 2-µ CMOS process - higher integration but no speakerphone test function. | Targeted at dual-handset or headset+handset configurations; lacks loudhearing mode and fixed 3-dB ringing step. | Select when dual analog inputs or programmable monitoring are required; not drop-in due to register map and MON protocol differences. |
| SLIC2163 | Integrated SLIC + codec in single package; −48 V line interface, no IOM®-2 support - replaces both line-side and terminal-side functions. | Used in central office equipment or IP-PBX gateways requiring analog line termination, not terminal-side voice processing. | Choose only for line-card applications; incompatible pinout, power architecture, and control interface. |
Compared with PSB2163T-V31TR, PSB2165T-V31TR adds dual-receive flexibility but removes loudhearing and simplifies ringing control, while SLIC2163 targets infrastructure rather than terminal design - making PSB2163T-V31TR optimal for cost-sensitive, single-transducer digital telephones requiring certified speakerphone performance.

FAQ
What is the maximum allowable supply voltage for PSB2163T-V31TR?
The absolute maximum rating is +5.5 V DC. Operation above +5.25 V or below +4.75 V violates the specified operating range and may cause undefined behavior in analog front-end gain stages and D/A converter linearity. The device is characterized for 8 kHz sampling only within the +5 V ±5 % window.
Does PSB2163T-V31TR support both IOM®-2 and serial interfaces simultaneously?
No - the interface mode is selected at power-up via the CAM bit in the General Configuration Register (GCR). IOM®-2 mode uses IOMD/IOMC pins; serial mode uses DCLK/DDATA and requires external clock synchronization. Both modes share the same command register structure but differ in framing and MON channel implementation.
How is speakerphone echo cancellation implemented in PSB2163T-V31TR?
It uses a fully digital, coefficient-programmable FIR filter in the ARCOFI® Signal Processor with separate TX/RX coefficient RAM banks. Echo cancellation is adaptive via AGCX/AGCR feedback loops and does not require external memory or host processor intervention during active calls.
Can the loudspeaker output drive an 8 Ω load directly?
Yes - the LSPK pin delivers up to 120 mW into 8 Ω at THD <1% with 5 V supply, verified per Section 110 (Analog Front End Characteristics) of Revision 06.95. No external amplifier is needed for basic handsfree operation, though external boost is recommended for >85 dB SPL.
