epon datasheet tk3715
The TK3715 chip for Optical Network Units (ONU) is an IEEE 802.3ah-compliant System-on-Chip (SoC) Ethernet Passive Optical Network (EPON) Bridge. The TK3715 supports all the functions needed to comply with the China standard for EPON. It provides high-speed, fiber optic broadband access for residential and business CPE (Customer Premises Equipment) ONUs. The auto-sensing Turbo-EPONTM mode operates at 1.25GHz downstream with legacy systems and 2.5GHz downstream with Turbo-EPON OLTs, such as the TK3723. The TK3715 is compatible with all Teknovus OLT chipsets. The TK3715 is cost-optimized for markets using the China standard for EPON. The high level of integration in the TK3715 greatly simplifies ONU design. The TK3715 contains an 802.3ah EPON MAC, a SerDes, line-rate L2/L3/L4 classification and filtering, China EPON decryption, Forward Error Correction (FEC), integrated packet buffering, two independent subscriber ports and an embedded processor. The processor supports a sophisticated ONU management system, including alarms, provisioning, DHCP and IGMP functions for a stand-alone IPTV solution at the ONU. Glueless interfaces are provided for an external EPON transceiver, FLASH and 10/100/1000 PHYs.
