FOA4400

PRODUCT Semiconductor Solutions for High Speed Communication and Fiber Optic Applications FOA4400 16:1 MUX Multiplexer with Clock Multiplication Unit MUX 39.8 - 43 Gbit/s, 5.5 V BRIEF FOA9400 1:1 FIFO Data Synchronization FIFO 2.5 - 2.7 Gbit/s, 5.5 V FOA5400 2:16 DEMUX Demultiplexer DEMUX 39.8 - 43 Gbit/s, 5.5 V FOA5401 1:2 CDR Clock and Data Recovery with 1:2 Demultiplexer CDR 39.8 - 43 Gbit/s, 5.5 V The 40 Gbit/s transceiver chipset (MUX+FIFO and CDR+DEMUX) provide highly integrated SerDes (SERializer-DESerializer) functionality with a 1:16 ratio. The 16 times 2.5 Gbit/s data signals are multiplexed to a single serial 40 Gbit/s data stream and vice versa. The devices support datarates from 39.8 Gbit/s up to 43 Gbit/s (OC-768/STM-256) with optional FEC (Forward Error Correction). All four chips are manufactured in Infineon's leading-edge Silicon-Germanium B7HF technology enabling low power consumption. The multiplexer FOA4400, FIFO FOA9400, demultiplexer FOA5400 and CDR FOA5401 feature CML interfaces, integrated VCOs (Voltage-Controlled Oscillator) and two reference clocks (622 MHz/2.5 GHz). The FOA4400 incorporates the CMU and selectable 20 GHz and 40 GHz clock outputs, whereas optional data synchronization is provided by the FOA9400. The FOA5400 and FOA5401 integrate CDR and demultiplexing functionality with extremely high input sensitivity.
