JL5104

Overview

The JL5104 is an 4-port fast Ethernet switch with RMII interface. It supports the QoS functions with four-level priority queues that ensure the performance of some real-time network applications.

The JL5104 integrates a 2K-entry address lookup table and a 4-way associative hash algorithm that validates input values, avoids hash collisions, and maintains forwarding performance. The supported maximum length of a data packet is 4097 bytes. Withthree types of independent storm filters, the JL5104 can filter packet storms. The JL5104 also integratesan intelligent switch engine that solves the Head-of-Line blocking problems.

The JL5104 supports 16 VLAN groups that can be  configured as port-based VLANs and/or 802.1Q tagbased

VLANs.

Typical Applications

? 4-Port Switch (10BASE-T and 100BASE-TX)

? HomePNA/HomePlug bridge

? Set-Top Box/TV

Features

? Up to 3x10BASE-T/100BASE-TX Ethernet ports + 1 RMII port

? Non-blocking wire-speed reception and transmission and

non-HOL forwarding

? L2 switching with 2K entry L2 Mac table, hash-based 4-way,

16 entry hash collision CAM, and 64 entry L2 multicast table

? Jumbo frame support, up to 4097 bytes

? 728K bits packet buffer and supports full mesh test from

64B to 1518B

? MIBs cover TX/RX packet/bytes counter, UC/MC/Flood

packet/bytes counter, packet CRC error counter, and

drop counter

? Supports high-performance QoS function on each port

? Supports Queue Management Operations

? 16 entry VLAN groups

? Flexible 802.1Q port/tag-based VLAN

? 16 VLANs are selected from a "cam-type-matching"

? Supports hardware loop detection function with LEDs

and buzzer to indicate the existence of a loop

? Flexible LED indicators

? Supports Ingress/Egress port mirror

? Multicast/Broadcast storm control with separate token

buckets for flooding, broadcast, and multicast packets

? Multicast/Broadcast storm control is either packet or

byte-based, configurable per egress port

? 32 entry L2 classification table for advanced application

? Physical layer port Polarity Detection and Correction function

? Single 3.3V power input can be transformed by integrating

LDO regulator to generate 0.9V from 3.3V via a low-cost

external Diode

? 25 MHz crystal or 3.3V OSC input

? 48-pin QFN package for 4 port FE Switch
