Product details
Overview
DP83867CSRGZT from Texas Instruments is a commercial-grade 10/100/1000BASE-T Ethernet PHY transceiver in a 48-pin VQFN package, supporting RGMII and SGMII MAC interfaces, delivering <90ns TX / <290ns RX latency, 457mW full-power operation, and IEEE 1588 Start-of-Frame detection for industrial time-sensitive networking applications.
For engineers reviewing the DP83867CSRGZT datasheet, DP83867CSRGZT pinout, DP83867CSRGZT application, or DP83867CSRGZT equivalent, this page delivers verified electrical specs, thermal metrics, I/O voltage flexibility (1.8V/2.5V/3.3V), ESD immunity (±6kV HBM on MDI pins), and TSN-compliant timing behavior - all validated for motor drives and factory automation designs.
Technical Context
The DP83867CSRGZT implements a full IEEE 802.3-compliant PMD sublayer with integrated MDI termination resistors and programmable MAC interface impedance. It supports dual-clock domains: 25MHz crystal input (XI/XO) and 125MHz GTX_CLK/RX_CLK for RGMII, plus 625MHz differential SGMII clock output (SGMII_COP/CON).
Its deterministic latency architecture enables Time-Sensitive Networking via IEEE 1588 Start-of-Frame Detect with ±16ns transmit and ±8ns receive SFD variation at 100Mbps, and it provides cable diagnostics, WoL packet detection, and RJ45 mirror mode for physical-layer debugging.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
DP83867CSRGZT uses a 48-pin VQFN (RGZ) package, 7 mm × 7 mm, with exposed thermal pad (DAP = GND). Pin functions include dual-mode MAC interface (RGMII/SGMII), JTAG debug, MDIO management, configurable GPIOs, LED drivers, and eight MDI differential pairs (TD_P/A–D, TD_M/A–D).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TX_D0–TX_D3, GTX_CLK | RGMII Transmit Interface | Synchronous data and clock inputs from MAC - requires matched trace lengths for skew control |
| RX_D0–RX_D3, RX_CLK | RGMII Receive Interface | Recovered data and clock outputs to MAC - supports 2.5/25/125 MHz modes per speed grade |
| SGMII_SIP/SIN, SGMII_SOP/SON, SGMII_COP/CON | SGMII Differential Interface | AC-coupled 625 MHz serial interface - eliminates timing skew issues of parallel RGMII at high density |
| TD_P_A / TD_M_A – TD_P_D / TD_M_D | MDI Differential Pairs | Four twisted-pair lanes for 1000BASE-T - integrated termination reduces BOM count and layout complexity |
| MDC / MDIO | IEEE 802.3 Management Interface | 25 MHz serial bus for register configuration and link status monitoring - pull-up required on MDIO |
| INT/PWDN | Interrupt / Power-Down Control | Open-drain interrupt output or active-low power-down entry - enables low-power sleep states in connected devices |
Key Features
| Feature | Design Value |
|---|---|
| 16 programmable RGMII delay modes | Compensates for PCB trace length mismatches between clock and data lines - eliminates need for external delay ICs |

| Configurable I/O voltage (1.8V/2.5V/3.3V) | Matches host processor I/O domain without level shifters - simplifies interface to SoCs and FPGAs |
| Start of Frame Detect for IEEE 1588 | Hardware-accelerated timestamp trigger - enables sub-microsecond time synchronization accuracy in TSN networks |
| Cable diagnostics | Detects opens, shorts, and pair swaps up to 150m - reduces field service time for industrial network deployments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP83867ISRGZ | Industrial temperature range (–40°C to +85°C); identical pinout and feature set | Required for uncontrolled ambient environments such as outdoor control cabinets or mobile machinery | Select DP83867ISRGZ when operating outside 0°C–70°C or requiring extended thermal qualification |
| Marvell 88E1512-B0-NNB2I000 | Supports SGMII/RGMII but lacks integrated MDI termination; lower ESD rating (±4kV HBM) | Used in cost-sensitive telecom access equipment where external termination is acceptable | Choose Marvell 88E1512 only if board space allows discrete termination and thermal margin exceeds 85°C |
Compared with DP83867ISRGZ, DP83867CSRGZT trades extended temperature capability for lower cost and qualification scope; compared with Marvell 88E1512, it delivers higher integration (on-die termination), superior ESD robustness, and tighter latency control - making it preferred for deterministic industrial Ethernet.

FAQ
What is the maximum operating junction temperature for DP83867CSRGZT?
The DP83867CSRGZT has a maximum operating junction temperature of 90°C under commercial conditions. Its thermal resistance (RθJA) is 30.8°C/W in the RGZ package, and the device includes junction-to-board (RθJB = 7.5°C/W) and junction-to-case (RθJC(bot) = 1.4°C/W) metrics to support thermal design validation. Derating is required above 70°C ambient.
Does DP83867CSRGZT support both RGMII and SGMII simultaneously?
No, DP83867CSRGZT supports RGMII or SGMII - not both concurrently. The interface mode is selected at power-up via hardware configuration pins (GPIO_0/GPIO_1) or software register settings. Each mode uses dedicated pins: RGMII uses TX_D0–TX_D3 and RX_D0–RX_D3, while SGMII uses differential SGMII_SIP/SIN and SGMII_SOP/SON pairs.
What clock sources does DP83867CSRGZT accept for its XI input?
The DP83867CSRGZT XI pin accepts a 25MHz fundamental-mode crystal (50ppm tolerance) or a 25MHz CMOS oscillator with 1.5–1.9Vpp swing. When using an oscillator, XO must be left floating. The internal PLL generates all required frequencies (25MHz, 125MHz, 625MHz) from this reference, eliminating need for external clock generators.
How is Wake-on-LAN implemented on DP83867CSRGZT?
DP83867CSRGZT implements Wake-on-LAN via hardware detection of magic packets and user-defined pattern matches on the MDI interface. The INT/PWDN pin serves dual function: when configured as PWDN, asserting it low places the PHY in ultra-low-power state while retaining WoL detection circuitry active. Register-controlled filtering enables selective packet recognition without host CPU involvement.
Can DP83867CSRGZT operate with a 1.8V-only I/O supply?
Yes, DP83867CSRGZT supports 1.8V VDDIO operation with VIH = 0.7×VDDIO and VOL = 0.2V (IOL = 1mA), meeting standard 1.8V logic thresholds. All digital I/O pins (RGMII, MDIO, GPIO, JTAG) are compatible, and the device automatically adapts drive strength and input thresholds - no external level shifters required when interfacing to 1.8V SoCs or FPGAs.
