Lantiq™ FALC™ ON FTTx System-on-Chip Family

Topology: Flyback
Input Voltage (min.): 27.00 V
Input Voltage (max.): 58.00 V
Output 1: 12.00 V / 1.200 A


The Lantiq™ FALC™ ON FTTx family of GPON ONU ICs is a scalable, highly integrated, cost- optimized and low-power system-on-chip solution that can be used in all FTTx deployment scenarios. The ICs provide an intelligent and cost-effective solution for managing the optical interface. In fact, the overall optical system performance exceeds the levels defi ned by the ITU-T G.984.2 standard.The optical side of a FALC™ ON FTTx device directly connects to a Bi-Directional Optical Sub- Assembly (BiDi OSA/BOSA) component, a photonic IC, or an optical transceiver module. The client side provides up to four GE interfaces for data traffi c. Integrated 10/100/1000BASE-T Ethernet PHY modules on the SoC enable direct interfacing with standard magnetics for two 1000BASE-T or four 10/100BASE-T links. On-chip voice processing, used with external SLIC devices, allows up to four FXS ports to be enabled. The comprehensive SoC design includes a burst-mode laser driver, post amplifi er and clock and data recovery, as well as a GPON ONU MAC and an on-chip CPU.
