KSZ8041NLI
General Description
The KSZ8041NL is a single supply 10Base-T/100Base-TX Physical Layer Transceiver, which provides MII/RMII interfaces to transmit and receive data. A unique mixed signal design extends signaling distance 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.
The KSZ8041NL represents a new level of features and performance and is an ideal choice of physical layer transceiver for 10Base-T/100Base-TX applications.
The KSZ8041RNL is an enhanced RMII version of the KSZ8041NL that does not require a 50MHz system clock. It uses a 25MHz crystal for its input reference clock and outputs a 50MHz RMII reference clock to the MAC. The KSZ8041NL and KSZ8041RNL are available in 32-pin, lead-free MLF® QFN per JDEC packages See Ordering Information.
