Note:
This pin can be factory configured to provide an external trace tone input. This allows an external sine wave signal to modulate the laser output
power (AM). This input can be used simultaneously with the internal SBS suppression dither function.
This input will accept a signal amplitude between 0 and 1Vpp and has a -3dB frequency bandwidth of approximately 3KHz to 2MHz.
The transfer function is not controlled so that the user must monitor the resulting AM and adjust the input signal amplitude so as to produce
the required modulation depth. This input is internally AC coupled. Absolute maximum input is 3Vpp.
Mechanical Detail (dimensions in mm)
• 14 way Pin Connector designed to mate with Samtec P/N ASP-113466-019 or equivalent.
• Module attached with 4 X M2 screws, clearance hole in ITLA, threaded in user housing.
The module should be mounted to a flat heat sink or thermal pathway for correct device operation. The module thermal
management should ensure that the case temperature does not exceed 75ºC at the worst case end of life dissipation figure
of 5.5 Watts.
