IC-HK Datasheet, PDF (1/8 Pages) IC-Haus GmbH – 155MHz LASER SWITCH

iC-HK, iC-HKB
155 MHz LASER SWITCH
FEATURES
o Laser switch for frequencies from CW up to 155 MHz
o Spike-free switching of the laser current
o Dual switching inputs with independent current control
o Operates as a voltage-controlled current source
o Pulsed operation with up to 700 mA per channel
o CW operation with up to 150 mA per channel
o Simple power control at pin CI
o Control to the mean of the laser power in conjunction with
iC-WK/L (CW laser diode driver)
o Supplement to iC-WK/L for pulsed operation
o Thermal shutdown
o Protective ESD circuitry
o iC-HKB for driving blue laser diodes
o Option: extended temperature range
