PC Board Mount Dual-Transmitter

3G-SDI and HD-SDI, 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 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 4. Also, the host PCB for the board mount

dual-transmitter

requires 4.7 K to 10 KΩ pull-up resistors for TX1_FAULT, TX2_FAULT, SCA and SDL lines.

Fiber Compatibility

The Dual transmitter is capable of error free signal detection at 2 to 1000 meters with OM3 50/125

μm fiber, 2 to 220

meters with

OM2 50/125 μm fiber, and at 2 to110 meters with OM1 62.5/ 125 μm fiber, for 3G-SDI data rate

Electrostatic Discharge (ESD)

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

described JEDEC EIA JESD22-A114-A, Class 1C (<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 dual-

transmitter prior to insertion to the host board. To protect the dual-transmitter, 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 board mount dual-transmitter 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

dual-transmitter may be subject to system-level ESD requirements.
