Using the EPC21601, if the duty ratio is 0.1% and pulse on-time is 5~10ns, is it possible to drive the VCSEL with a current, say 40A or 80A?
The manual book states the situation of 15 A peak current with a 50 MHz clk. And I wonder that, given the same on-time(10 ns) with a much longer off-time and the duty-ratio is 0.1%, can this IC endure a current of several tens of ampere?
Besides may I ask that, if the answer is no, is the issue mainly about thermal or electrical breakdown? And is it possible to analyze the issue from the manual book?
Thanks a lot for your time, I would appreciate any response!
