KSZ9031RNXIA 4/4 Transceiver Full Ethernet 48-QFN (7x7) Surface
MountGeneral DescriptionThe KSZ9031RNX is a completely integrated triple-speed
(10BASE-T/100BASE-TX/1000BASE-T) Ethernet physicallayer transceiver
for transmission and reception of data on standard CAT-5 unshielded
twisted pair (UTP) cable. The KSZ9031RNX provides the Reduced
Gigabit Media Independent Interface (RGMII) for direct connection
to RGMII MACs in Gigabit Ethernet processors and switches for data
transfer at 10/100/1000 Mbps. The KSZ9031RNX reduces board cost and
simplifies board layout by using on-chip termination resistors for
the four differential pairs and by integrating an LDO controller to
drive a low-cost MOSFET to supply the 1.2V core. The KSZ9031RNX
offers diagnostic features to facilitate system bring-up and
debugging in production testing and in product deployment.
Parametric NAND tree support enables fault detection between
KSZ9031 I/Os and the board. The LinkMD® TDR-based cable diagnostic
identifies faulty copper cabling. Remote and local loopback
functions verify analog and digital data paths. The standard
KSZ9031RNX is available in a 48-pin, lead-free QFN package, and the
AEC-Q100 automotive qualified parts, KSZ9031RNXUA/UB and
KSZ9031RNXVA/VB, are available in a 48-pin lead-free VQFN
(wettable) package. Features• Single-Chip 10/100/1000 Mbps Ethernet Transceiver Suitable for
