Product details
Overview
DP83867CRRGZR from Texas Instruments is a commercial-grade (0°C to +70°C), 48-pin VQFN Ethernet PHY transceiver supporting 10/100/1000BASE-T over twisted-pair media. It implements RGMII MAC interface, delivers ultra-low RGMII latency (TX < 90 ns, RX < 290 ns), consumes 457 mW at full operation, and provides IEEE 1588 Start of Frame detection for time-sensitive networking in industrial automation systems.
For engineers reviewing the DP83867CRRGZR datasheet, DP83867CRRGZR pinout, DP83867CRRGZR application, or DP83867CRRGZR equivalent, key selection considerations include its RGMII-only interface, 7 mm × 7 mm QFN package, 1.8V/2.5V/3.3V I/O voltage configurability, ±6 kV IEC 61000-4-2 ESD rating on MDI pins, and integrated cable diagnostics for field-deployable wired infrastructure.
Technical Context
The DP83867CRRGZR implements a fully compliant IEEE 802.3 PHY layer with integrated PMD sublayers for 10BASE-Te, 100BASE-TX, and 1000BASE-T. Its RGMII interface operates with GTX_CLK at 125 MHz and RX_CLK at 125/25/2.5 MHz depending on speed mode, while supporting 16 programmable RGMII delay modes for timing alignment.
It integrates MDI termination resistors, configurable MII/GMII/RGMII termination impedance, and Wake-on-LAN packet detection. The device uses a 25 MHz crystal or oscillator input (XI/XO) and provides a synchronous CLK_OUT for system clock distribution, enabling precise IEEE 1588 timestamping via Start of Frame Detect.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Ethernet PHY applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DP83867IRRGZ | Industrial temperature grade (–40°C to +85°C); identical RGMII interface, pinout, and feature set. | Required for outdoor or uncontrolled-temperature deployments; same PCB layout but higher thermal derating margin. | Select DP83867IRRGZ when ambient exceeds 70°C or extended reliability qualification is mandated. |
| KSZ9031RNXCA | 48-pin QFN, 10/100/1000BASE-T, RGMII, but lacks TSN features (no IEEE 1588 SoF detect) and offers only ±4 kV MDI ESD. | Suitable for cost-sensitive non-TSN applications; lower ESD immunity limits use in high-noise factory floors. | Choose KSZ9031RNXCA only if TSN and ≥±6 kV ESD are not required; verify RGMII timing compatibility during validation. |
Compared with DP83867CRRGZR, DP83867IRRGZ extends operating range without design changes, while KSZ9031RNXCA trades TSN capability and robustness for lower unit cost-making DP83867CRRGZR optimal for commercial-grade TSN edge nodes where precision timing and field reliability are mandatory.

FAQ
What is the maximum RGMII data rate supported by DP83867CRRGZR?
DP83867CRRGZR supports full 1000BASE-T operation with RGMII interface running at 125 MHz GTX_CLK and 125 MHz RX_CLK. It achieves this using 4-bit nibble-wide data transfers synchronized to source clocks, enabling 1 Gbps throughput with ultra-low latency (TX < 90 ns, RX < 290 ns). The device does not support 2.5G or 5G Ethernet modes.
Does DP83867CRRGZR support MII or GMII interfaces?
No, DP83867CRRGZR supports RGMII only. Its RGZ (VQFN-48) package variant is specifically designed for RGMII connectivity. MII and GMII interfaces are available only on the PAP (HTQFP-64) variants like DP83867IRPAP. Attempting to use MII/GMII signals on DP83867CRRGZR will result in functional failure due to missing pins and internal routing limitations.
What is the purpose of the RBIAS pin on DP83867CRRGZR?
The RBIAS pin on DP83867CRRGZR connects to an external 11 kΩ ±1% resistor to ground, establishing a precision bias current for internal analog circuitry including the MDI driver and receiver front-end. This resistor calibrates transmit amplitude, receive sensitivity, and common-mode voltage-ensuring consistent 1000BASE-T signal integrity across voltage and temperature variations.
Can DP83867CRRGZR operate with a 1.0V core supply?
Yes, DP83867CRRGZR requires a 1.0V ±15.5% analog supply (VDD1P0) for its digital core and PLL. This rail must be decoupled with both 1 µF and 0.1 µF capacitors to ground per VDD1P0 pin. The device also needs separate 1.8V (VDDA1P8), 2.5V (VDDA2P5), and configurable I/O (VDDIO) supplies-all independently decoupled as specified in Section 9.3 of the datasheet.
How does the cable diagnostics feature work in DP83867CRRGZR?
DP83867CRRGZR performs Time-Domain Reflectometry (TDR)-based cable diagnostics by injecting calibrated pulses onto each MDI pair and analyzing reflected waveforms. It reports open-circuit distance, short-circuit location, and impedance discontinuities up to 150 meters-accessible via MDIO registers (e.g., CRGCR[15:0]). Results require no external tools and integrate directly into host firmware for automated field validation.
