GENERAL DESCRIPTION
The NetPHY™ 4LP device is a highly integrated, low power 10BASE-T/100BASE-TX/FX Quad Ethernet transceiver. The NetPHY™ 4LP device includes integrated RMII, ENDECs, Scrambler/Descrambler, and full-featured Auto-Negotiation with support for Parallel Detection and Next Page. Port 3 can be configured as a 100BASE-FX transmitter to output an NRZI PECL level signal. Each receiver has an adaptive equalizer/DC restoration circuit for accurate clock/data recovery on the 100BASE-TX signal at different cable lengths and can perform to 125 m and beyond.
DISTINCTIVE CHARACTERISTICS
■ Four 10/100BASE-TX Ethernet PHY transceivers
■ Supports RMII (Reduced MII) interface
■ 125 meter (m) MLT-3 and Baseline Wander operation
■ Low power consumption
— 1.3 Watt (W) typical (1:1 magnetics)
— 1.2 W typical (1.25:1 magnetics)
■ Power management modes:
— Selectable 1:1 or 1.25:1 transmit transformer
— Unplugged - approximately 100 mW per port
— Power Down - approximately 3 mW per port
■ Single 3.3 V power supply with 5 V I/O tolerance
■ Patent-pending DC restoration technique reduces baseline wander susceptibility
■ Full and half-duplex operation with full-featured Auto-Negotiation function
■ Next Page register support
■ Automatic Polarity Detection during AutoNegotiation and 10BASE-T signal reception
■ Unique scramble seed per port reduces EMI in switch and repeater applications
■ One port supports 100BASE-FX function
■ Supports Inter Packet Gap as low as 40 ns for high throughput applications
■ No external filters or chokes required
■ Compliant with IEEE 802.3 standards for 100BASE-TX, 100BASE-FX, and 10BASE-T
■ Built-in loopback and test modes
■ Small 14 x 20 mm 100-pin PQR package
■ Small package allows side-by-side PHY layout
— Fits neatly behind quad magnetics
— Saves board space over larger 208 PQFP packages
■ Support for Industrial Temperature (-40°C to +85°C)
