DR-DG-12-MO
12 Gbps NRZ Medium Output Voltage Driver

PHOTLINE DRIVER

The Photline DR-DG-12-MO is a high performance versatile driver module
designed for 2.5 Gbps up to 12.5 Gbps data transmission with NRZ or RZ
format. It exhibits a 28 dB gain and can deliver an output signal up to 9 Vpp.
The Photline DR-DG-12-MO is a key component to obtain high quality 2.5
Gbps up to 12.5 Gbps eye diagrams with low rise and fall time, low jitter andhigh SNR. It operates from a single power supply for safety and ease of use,
and offers gain and cross point controls. It comes with K 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.
