PCB Mount Quad Transmitter

100 Mbps – 5 Gbps, MMF, 3.3V

Required Host Board Components

A power supply noise rejection filter as describe in SFP MSA is required on the host PCB to meet data sheet

performance. This is the same filter

incorporates an inductor which should be rated 400 mADC and 1 Ω series resistance

or better. It should not be replaced with a ferrite. The required filter is illustrated in Figure 5. Also, the host PCB for the

PCB mount transceiver r

equires 4.7 K to 10 KΩ pull-up resistors for TX_FAULT, SCA and SDL lines.

Fiber Compatibility

The transmitter

is capable of transmission at 2 to 550 meters with 50/125 μm fiber, and at 2 to 275 meters with 62.5/125

μm fiber, for 1.25 GBd Ethernet. It is capable of transmission up to 550m with 50/125 μm fiber and up to 300m with

62.5/125 μm fiber, for 1.0625 GBd Fiber Channel.

Electrostatic Discharge (ESD)

The transmitter is compatible with ESD levels found in typical manufacturing and operating environments as described

JDEC/EIAJESD22-A114-A, Class 1 (<2000Volts) HBM. Glenair recommends that devices are handled with ESD

precautions to limit exposure to below 500V HBM.

There are two design cases in which immunity to ESD damage is important. The first case is during handling of the

transmitter prior to insertion to the host board. To protect the unit, it’s important to use standard industry ESD handling

precautions. These precautions include using grounded wrist straps, work benches, and floor mats in ESD controlled

areas. The ESD sensitivity of the Glenair PCB mount transceiver is compatible with typical industry production

environments.

The second case to consider is static discharges to the exterior of the host equipment after installation, in which case the

transmitter may be subject to system-level ESD requirements.
