JL5110C,10口百兆交换机芯片 2*MAC 1 MII/RMII +1 RMII
Overview The JL5110 is an 8-port fast ethernet switch with 1 MII/ RMII interface and 1 RMII interface. It supports the QoS functions with four-level priority queues that ensure the performance of some real-time network applications.
The JL5110 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. With three types of independent storm filters, the JL5110 can filter packet storms. The JL5110 also integrates an intelligent switch engine that solves the Head-ofLine blocking problems.
The JL5110 supports 16 VLAN groups that can be configured as port-based VLANs and/or 802.1Q tagbased VLANs.
Typical Applications
• 10-Port Switch (10BASE-T and 100BASE-TX)
• HomePNA/HomePlug bridge
• Set-Top Box/TV
• Up to 8x10BASE-T/100BASE-TX Ethernet ports + 1 MII/RMII port and 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
• STP: supports BPDU and LLDP parsing. Supports port status (forarding, listening, blocking assignment by SW)
• 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
• 88-pin QFN package for 10-port FE Switch
