Product Description

Description

SE0162 is a highly integrated ASIC that is designed for transparent transmission of Ethernet data frame via E1 Channel. SEO162 is capable of point-to-point transmission of Ethernet data frame via one E1 connection or synchronous serial connection. It also supports standard MII interface and E1 interface. Combining with less peripheral circuits, it can form a converter from Ethernet to E1. The main function of the sending side is Ethernet frame buffer, which frames and sends according to HDLC protocol; the main function of the receiving side is to acknowledge the clock of receiving E1, frame alignment of serial data and its decoding via HDLC protocol, and framing of Ethernet frames and its sending.

Features

  • Suitable for transparent transmission of Ethernet frames via one way of E1 connection or bit synchronous serial interface
  • Ethernet interface supports 10/100M full-duplex /half-duplex MII interface complying with IEEE 802.3 protocol standards.
  • MII Interface is capable of connecting PHY and MAC devices
  • Supports IEEE802.3 flow control
  • MAC checks and handles with receiving frames, including FCS check, frame size check, dismissing of wrong frames, and alarming function about wrong FCS
  • Supports frame size of 64 bytes to 1536 bytes and frame including VLAN bytes
  • WAN interface supports HDLC protocol, supports bit synchronous HDLC interface, provides NRZ codes serial interface, with max timing of 40M and external clocking
  • HDLC interface supports DTE timing mode
  • E1 interface complies with ITU-T G.703、G.704 and G.823 standards ( able to connect with bridge chip such as RJ017、AT8993、xBRIDGE2.0)
  • E1 interface module includes built-in clock recovery circuits and HDB3 coding and decoding circuits
  • SDRAM controller is integrated in the chip, which can seamlessly connect with standard 1M*16bit SDRAM device such as IS42S16100、K4S161622D、HY57V161610.
  • Ethernet side has sending and receiving frame counter and wrong frame counter
  • WAN side has sending and receiving frame counter and wrong frame counter
  • SDRAM testing function, which can check out connecting errors and store block errors. Self testing when power up with indicator light
  • WAN connection self testing. WAN side Loopback or local circulation via remote chip to examine line faults
  • Six types of loopback tests
  • Remote reset function and remote network management monitoring function
  • Providing user-defined network management frames
  • Power failure detection and network management returning function. Local signaling when power failure of the other end
  • Providing SPI network management interface
  • LQFP100 encapsulation
  • Adopting 3.3V ±10%power supply for the entire chip. The input pin is compatible with 5V
