11 Ethernet PHY - KSZ8041RNL
11.1 General Description
The KSZ8041RNL is a single supply 10Base-T/100Base-TX Physical Layer Transceiver
with RMII support. It uses a 25MHz crystal for its reference clock and outputs a 50MHz
RMII reference clock to the MAC.
with RMII support. It uses a 25MHz crystal for its reference clock and outputs a 50MHz
RMII reference clock to the MAC.
The KSZ8041RNL employs a unique mixed signal design to extend cable reach while
reducing power consumption. HP Auto MDI/MDI-X provides the most robust solution for
eliminating the need to differentiate between crossover and straight-through cables.
