DriverFeatures

Description

The 10NS-800DR is a high speed current driver board
capable of delivering 800mA in 10ns to an
optoelectronic laser or amplifier. The board accepts
Butterfly packaged devices with TEC operating
parameters up to 2.3V and 3A. The anode and cathodeof the optoelectronic device have to be floating (notconnected to case). The input control signals are in
LVPECL logic, accessible via SMA or 14 pins connector.
The current is send to the device when the “SignalControl” is set at logical level one, and trigged on thepositive transition of the “Clock” signal. Drive current
can be dynamically adjusted thanks to a 4 bits digitalcontrol command. Power supply voltages are +/- 5V
and +/-15V. The board is equipped with its own heatsink.

 High speed, tr = 10ns typ.
 800mA drive capability On demand current dynamic setting Pre bias

Function
Automatic mode (sc switch at 0):“1” level allows current Ip to pass in optoelectronic
device, trigged on positive transition of Clock signal. Logical “0” level stops the current.
Semi-automatic mode (sc switch at 1): No trigger function of Clock signal. A “1” level
allows current Ip to pass in optoelectronic device. Logical “0” level stops the current.
Active on positive transition. On automatic mode, synchronizes SCl, A, B, C and D signals.

Current dynamics
Figures 1 and 2 show the Ip and Ip maximum current dynamics for two different board settings.
Ip is set manually between IpL and IpH using Ip+ / Ip- buttons. The Ip value is automatically stored in a non volatilememory. Current value can be monitored through a test point (connect a volt meter).
On board switch “SW7” splits the current dynamic in two parts, with a ratio of 2 for the maximum current.
Figures 1 and 2 bellow show the current Ip+Ip (mA) as function of Ip and Ip commands.

Handling
This product is sensitive to electrostatic discharge and should not be handled except at a static free workstation. Take
precautions to prevent ESD; use wrist straps, grounded work surfaces and recognized anti-static techniques whenhandling the 10NS-800DR module.
Care should be taken to avoid supply transient and over voltage. Over voltage above the maximum specified in absolute
maximum rating section may cause permanent damage to the device.
