KSZ9031RNXCA-TR Description

Short technical summary and product information.

The Microchip Technology KSZ9031RNXCA-TR is a single-chip 10/100/1000 Mbps Ethernet transceiver designed for IEEE 802.3 applications. It supports RGMII timing according to Version 2.0, with I/O voltage tolerance for 3.3V, 2.5V, and 1.8V. Auto-negotiation automatically selects the highest link-up speed and duplex mode.

 

Key electrical features include on-chip termination resistors for differential pairs, an on-chip LDO controller supporting single 3.3V supply operation, and jumbo frame support up to 16 KB. It also provides a 125 MHz reference clock output and features an energy detect power-down mode for power saving. Wake-On-LAN (WOL) support with custom-packet detection is included, along with programmable LED outputs for link, activity, and speed indication.

 

For diagnostics and reliability, the transceiver incorporates baseline wander correction, LinkMD TDR-based cable diagnostics, parametric NAND tree support for fault detection, and loopback modes. It also features automatic MDI/MDI-X crossover and automatic correction for pair swaps, skew, and polarity. Management is handled via the MDC/MDIO interface, and an interrupt pin option is available.

 

The device operates within a temperature range of 0 to 70°C and is housed in a 48-VFQFN Exposed Pad package, with a supplier package of 48-QFN (7x7). Mounting is via surface mount.
