DP83848IVV - 10/100 Ethernet PHY Transceiver | Texas Instruments
MPN: DP83848IVV ✓ فعالDP83848IVV جائزہ
An Ethernet PHY (Physical Layer Device) is a transceiver IC that sits between a MAC controller and the copper media (twisted pair), handling analog line driving/receiving, clock recovery, link monitoring, and 10BASE-T/100BASE-TX encoding/decoding. PHYTERs are a category of Ethernet PHYs that emphasize robust industrial-grade operation, sitting within the broader Ethernet controller hierarchy: PHY -> transceiver -> network interface device -> communication IC -> semiconductor.
Key features of the DP83848IVV include integrated 100BASE-TX/FX physical coding sublayer (PCS) and physical media attachment (PMA), 3.3V single-rail operation with 2.5V internal LDO, Auto-MDIX crossover detection, Energy Detect Plus power-down modes, and 4 kV ESD tolerance on the MDI pins. The device also features low-latency (sub-100ns) MII throughput, hardware pause-frame support for flow control, and an IEEE 1149.1 JTAG boundary-scan port for board test. The 48-LQFP package provides a thermally efficient surface-mount footprint with 31.4 C/W typical junction-to-ambient resistance.
Architecture-wise, the DP83848IVV combines a DSP-based receive path with adaptive equalization to recover signals over >150m of CAT-5 cable, a 125 MHz PLL for 100BASE-TX clocking, and a 25 MHz crystal interface or external clock input. Internal voltage regulation simplifies power tree implementation by accepting a single 3.3V supply.
The DP83848IVV is designed for industrial Ethernet nodes, factory automation controllers, motor drives with EtherCAT/PROFINET bridges, building-automation gateways, IP-based surveillance cameras, and any embedded MCU/MPU with MII/RMII needing 10/100 connectivity. Its -40C to +85C industrial temperature grade supports deployment in harsh environments.
When designing with the DP83848IVV, follow TI's reference layout for the magnetics and 49.9 ohm 1% termination resistors as specified in the datasheet application section. Use a 25 MHz crystal or feed a clean external CMOS clock; keep the MDI traces length-matched within 50 mils and 100-ohm differential-impedance controlled for best EMI margin.

Industrial Ethernet Nodes
The DP83848IVV's -40C to +85C industrial temperature grade and 48-LQFP compact footprint make it ideal for factory-floor PLCs and remote I/O blocks requiring 10/100 Ethernet connectivity. Its integrated Auto-MDIX eliminates crossover-cable mistakes by technicians in field installations. Placed between an MCU/MAC and the RJ45 magnetics, it provides 100 m CAT-5 reach with on-die adaptive equalization that recovers signals cleanly in electrically noisy cabinet environments. The 3.3V single-rail operation simplifies power-tree design on 24V-input industrial boards.

Motor Drives with EtherCAT/PROFINET Bridges
Industrial servo drives and variable-frequency motor drives need 10/100 Ethernet to host PLCs over EtherCAT, PROFINET, or Ethernet/IP. The DP83848IVV supports these protocols via the MII interface to protocol-specific MAC ASICs from Beckhoff, Siemens, or HMS. Its industrial temperature rating ensures stable operation in sealed drive enclosures reaching 70C+. The 48-LQFP-7x7 fits within typical 50x80mm motor control boards, leaving room for IGBT/MOSFET power components nearby.

IP Surveillance Cameras
Outdoor PoE-powered IP cameras need a robust 10/100 PHY operating in -40C ambient temperature extremes. The DP83848IVV's industrial temperature grade and Auto-MDIX simplify installation, while its energy-detect power-down mode enables <100 mW standby consumption. Placed between the image sensor SoC's MAC and the RJ45 jack, it streams 1080p30 H.264/265 video at 100 Mb/s with sub-100-ns MII latency. The 48-LQFP package provides thermal headroom for sealed IP67 housings without additional heatsinking.

Building Automation Gateways
BACnet/IP, KNXnet/IP, and Modbus-TCP building-automation gateways require reliable 10/100 Ethernet in ceiling-mounted enclosures. The DP83848IVV's Auto-MDIX eliminates wiring mistakes in field installations by contractors unfamiliar with crossover cables. Its 3.3V single-supply operation simplifies power design on shared 24V building rails, and the 48-LQFP package with 7x7 mm footprint fits in compact DIN-rail gateway housings. JTAG support enables boundary-scan verification during board bring-up for reliable multi-year deployments.

Embedded Routers / IoT Gateways
Edge routers and IoT gateways with 10/100 WAN/LAN ports benefit from the DP83848IVV's low-latency MII throughput and hardware pause-frame flow control. The device pairs naturally with embedded Linux MCUs (i.MX RT, AM335x) for OpenWrt-based routers. Its energy-detect power-down reduces idle consumption below 50 mW when the cable is unplugged, critical for energy-star IoT products. The integrated 2.5V LDO saves the cost of an external regulator on space-constrained gateway boards.

Test & Measurement Equipment
Lab instruments such as oscilloscopes, spectrum analyzers, and protocol analyzers need reliable LXI-compliant 10/100 Ethernet connectivity for SCPI remote control. The DP83848IVV's IEEE 1149.1 JTAG interface simplifies board boundary-scan testing during manufacturing test, and its hardware pause-frame support enables lossless capture streaming. Placed between an FPGA MAC and the rear-panel RJ45 jack, it provides 100 Mb/s throughput sufficient for waveform upload in <2 seconds for typical 100 MB acquisitions.

ڈیزائن نوٹس
Follow TI's reference layout for the DP83848IVV: place the 49.9 ohm 1% termination resistors within 5 mm of the TD+/TD- and RD+/RD- pins. The differential MDI traces must be 100-ohm differential impedance and length-matched within 50 mils for IEEE 802.3u compliance. Keep analog and digital ground planes separated and join only at the EPAD ground pins. Use a 4-layer stack-up with a continuous ground plane beneath the device for best EMI performance.
Bypass each supply pin (AVDD33, DVDD33, IOVDD33) with a 0.1 uF X7R ceramic capacitor within 2 mm of the pin. Add a 10 uF bulk tantalum or ceramic at the device's main supply input. The internal 2.5V LDO requires a 0.1 uF + 10 uF bypass cap on the AVDD25 pin for PLL clean operation. Use a ferrite bead between digital and analog 3.3V rails to isolate switching noise.
Do not omit the 25 MHz crystal or external CMOS clock on X1/X2 - the PHYTER has no internal oscillator. Strapping pins (PHYAD, RBIN, AN) are read only at hardware reset; do not drive them with active signals during reset. Auto-MDIX requires Auto-Negotiation to be enabled. For fiber-only FX applications, choose the DP83848VF variant instead - the IVV supports FX only when the MDI pins are properly reconfigured via the FXD strap.
تعمیل کی معلومات
RoHS/REACH compliant only with /NOPB suffix. Standard DP83848IVV (without NOPB) is non-RoHS. Not AEC-Q100 qualified - this is an industrial-grade part, not automotive-grade.
