Preliminary and Proprietary www.wavesplitter.com Page 7of 9 Document Number: 95-0030-V1 2.5Gbps SFP Transceiver modules (with DDM function) WST-S3CDx4-Dx Series Required Host Board Components The MSA power supply noise rejection filter is required on the host PCB to meet data sheet performance. The MSA filter incorporates an inductor which should be rated 400mADC and 1 Ω serial resistance or better. It should not be replaced with a ferrite. The required filter is illustrated in Figure 3. The MSA also specifies that 4.7K to 10K Ω pull-up resistors for TX_FAULT, LOS, and MOD_DEF0,1,2 are required on the host PCB. Figure is the suggested transceiver/host interface. Typical Application Circuit +3.3V
