Product details
Overview
DIT4096IPW from Texas Instruments is a digital audio transmitter IC compliant with AES-3, IEC-60958, and EIAJ CP1201 standards, supporting up to 96kHz sampling rates, on-chip differential line driver (TX+/TX–), flexible serial audio interface (I²S/Left-/Right-justified), and dual-mode operation (software/hardware control). It serves as the AES-3 encoder and physical layer driver in professional audio digital interconnects.
For engineers reviewing the DIT4096IPW datasheet, DIT4096IPW pinout, DIT4096IPW application, or DIT4096IPW equivalent, key selection considerations include master clock rate support (256fS/384fS/512fS), dual-mode configuration flexibility, differential output compliance, channel status/user data handling, and TSSOP-28 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The DIT4096IPW integrates an AES-3 encoder, Bi-Phase Mark modulator, and balanced line driver. It accepts linear PCM audio via 3-wire serial port (SDATA/SYNC/SCLK) and multiplexes it with channel status, user (U), and validity (V) data into a standardized 192-frame AES-3 stream.
It operates in two mutually exclusive modes: Software mode uses a 4-wire serial control port (CS/CCLK/CDIN/CDOUT) to access 8-bit registers and 24-byte channel status buffer; Hardware mode configures functionality via dedicated pins (FMT0/FMT1/MODE/CLK0/CLK1), eliminating microcontroller dependency for fixed-function applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| AES-3 Compliance | Fully compliant with AES-3, IEC-60958, and EIAJ CP1201 - ensures interoperability with professional and consumer digital audio receivers. |
| Max Sampling Rate | 96kHz - supports high-resolution audio formats including DVD-Audio and studio-grade recording workflows. |
| Master Clock Input | 256fS, 384fS, or 512fS - enables precise timing alignment with common audio system clocks (e.g., 24.576MHz at 96kHz). |
| Line Driver Output | Differential TX+/TX– with ±30mA drive capability - meets AES-3 electrical requirements for twisted-pair cable transmission up to 10m. |
| Supply Voltages | VDD = +4.5V to +5.5V (nominal +5V); VIO = +2.7V to VDD - supports mixed-voltage system integration with 3.3V or 5V logic domains. |

| Dynamic Current | 22mA IDD at 96kHz - enables accurate power budgeting for real-time audio transmission subsystems. |
Pinout & Package
TSSOP-28 package (PW suffix), 4.4mm × 9.7mm body, 0.65mm pitch, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 17, 18 | TX–, TX+ | Differential AES-3 output pair - drives transformer-coupled or direct-connected balanced transmission lines per AES-3 spec. |
| 11, 12, 13 | SCLK, SYNC, SDATA | Audio serial port interface - accepts I²S/Left-/Right-justified PCM data with frame sync and bit clock. |
| 2, 3, 4, 5 | CDOUT, CCLK, CDIN, CS | Serial control port (Software mode only) - enables register read/write and channel status buffer access via SPI-like protocol. |
| 28 | MODE | Mode selection input - logic low = Software mode; logic high = Hardware mode; determines pin function mapping and configuration method. |
| 6 | MCLK | Master clock input - provides timing reference for internal AES-3 encoding, SCLK generation, and sample rate derivation. |
| 15 | RST | Active-low hardware reset - forces internal registers to default state and holds TX+/TX– at ground until SYNC edge detection. |
| 7, 19 | VIO, VDD | Separate I/O and core supplies - allows interfacing with 3.3V controllers while maintaining +5V core logic integrity. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital audio transmitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CS8406-DZZ | Single 3.3V supply (VDD = VIO = 3.3V); no hardware mode; supports S/PDIF only (not AES-3 differential) | Limited to consumer S/PDIF coaxial/optical output; lacks professional AES-3 compliance and differential drive | Select when cost-sensitive consumer audio design requires only S/PDIF and 3.3V operation. |
| AK4117VT | Supports 192kHz max sampling rate; includes jitter reduction PLL; requires external line driver for AES-3 | Higher sample rate capability but adds BOM complexity and board space due to external driver requirement | Select when ultra-high-resolution audio (192kHz) is mandatory and system-level jitter tolerance is tight. |
Compared with CS8406-DZZ and AK4117VT, the DIT4096IPW uniquely delivers full AES-3 differential compliance in a single TSSOP-28 package with dual-mode configurability - enabling both MCU-based flexibility and MCU-free simplicity without sacrificing professional interface fidelity.

FAQ
What is the maximum sampling frequency supported by the DIT4096IPW?
The DIT4096IPW supports a maximum sampling frequency of 96kHz, as confirmed in the device's Electrical Characteristics table and General Description section. This enables compatibility with high-resolution audio formats used in DVD-Audio, studio recording, and professional broadcast applications. The DIT4096IPW maintains full AES-3 and IEC-60958 compliance at this rate, and its master clock input accepts 256fS, 384fS, or 512fS configurations - for example, 24.576MHz at 96kHz. Operation beyond 96kHz is not supported.
Does the DIT4096IPW require an external line driver for AES-3 output?
No, the DIT4096IPW does not require an external line driver for AES-3 output. It integrates a fully compliant differential line driver on pins TX+ (18) and TX– (17), capable of delivering ±30mA into a 110Ω load with proper common-mode voltage and rise/fall time per AES-3 specifications. The datasheet explicitly states "ON-CHIP DIFFERENTIAL LINE DRIVER" as a key feature and confirms output voltage swing (VDD – 0.7V to VDD) under 30mA load. External transformers remain optional for isolation but are not required for basic compliance.
Can the DIT4096IPW operate without a microcontroller?
Yes, the DIT4096IPW can operate without a microcontroller when configured in Hardware mode (MODE = 1). In this mode, all configuration - including audio format (via FMT0/FMT1), master clock rate (CLK0/CLK1), mono/stereo (MONO/MDAT), and channel status inputs (CSS/COPY/L/AUDIO/EMPH) - is handled through dedicated logic-level pins. The datasheet states "HARDWARE MODE ALLOWS OPERATION WITHOUT A MICROCONTROLLER" as a core feature, and pin descriptions confirm direct control of AES-3 encoding parameters without serial programming.
What audio data formats does the DIT4096IPW support?
The DIT4096IPW supports Philips I²S, Left-Justified, and Right-Justified audio data formats, with word lengths configurable from 16 to 24 bits. In Software mode, format selection is programmable via Control Register 03H (JUS, DELAY, ISCLK, ISYNC bits); in Hardware mode, FMT0/FMT1 pins select among 24-bit Left-Justified, 24-bit I²S, 24-bit Right-Justified, or 16-bit Right-Justified. The datasheet's Table IV and Table V explicitly list these formats, and Figure 4 illustrates timing for all three major justification types - confirming native support without external translation logic.
Is the DIT4096IPW pin-compatible with other TI digital audio transmitters like the DIT4095?
No, the DIT4096IPW is not pin-compatible with the DIT4095 or other TI audio transmitters. The DIT4095 uses a 24-pin SOIC package and lacks several pins present on the DIT4096IPW - including dedicated hardware mode controls (FMT0/FMT1, CSS, COPY, L), mono-mode inputs (MONO, MDAT), and expanded channel status/user data pins (U, V, BLS). Pin count (28 vs. 24), pin functions (e.g., INT, BLSM, EMPH), and package type (TSSOP-28 vs. SOIC-24) differ fundamentally. The datasheets show no shared pinout mapping, and TI does not document drop-in replacement between these devices.
