DR-DG-10-MO-NRZ

12.5 Gbps NRZ Medium Output Voltage Driver Module

Photline Driver

The Photline DR-DG-10-MO-NRZ is a driver module specially designed for10 Gbps / 12.5 Gbps data transmission with NRZ format. It exhibits a 20 dB
gain and can deliver an output signal up to 8 Vpp.
The Photine DR-DG-10-MO-NRZ is a key component to obtain high quality
12.5 Gbps eye diagrams with high SNR, low jitter and short rise and fall time.
It operates from a single power supply for safety and ease of use, and offers
gain control over 3 dB. It comes with SMA type RF connectors (female in,male out) and with an optional heat sink.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional
operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure
to absolute maximum ratings for extended periods can adversely affect device reliability.
