V23836-C18-C63 Datasheet, PDF (11/13 Pages) Infineon Technologies AG – 1x9 Transceiver with Duplex SC Receptacle Single Mode 1300 nm 21 km SONET OC-3 / SDH STM-1
V23836-C18-C63, V23836-C18-C363 Product Specification – September 2004
This application note assumes Fiber Optic transceivers using 3.3V power supply and
SerDes Chips using either 3.3V or 5V power supply. It also assumes no self biasing at the
receiver data inputs (RD+/RD–) of the SerDes chip (Refer to the manufacturer Product
Specification for other applications).
Value of R1...R4 may vary as long as proper 50Ω termination to VEE or 100Ω
differential is provided. The power supply filtering is required for good EMI
performance. Use short tracks from the inductor L1/L2 to the module VCCRx/VCCTx.
Further application notes for electrical interfacing are available upon request. Ask for
Appnote 82.
We strongly recommend a VEE plane under the module for getting good EMI
performance.
The transceiver contains an automatic shutdown circuit. Reset is only possible if the
power is turned off, and then on again. (VCCTx switched below VTH).
