Part Number: LMG1020EVM-006 Other Parts Discussed in Thread: TIDA-01573 , LMG1020
I want to drive LD SPL TL90AT08 (IF = 40 A; tp = 100 ns; D = 0.01 %, Vop=11V) with an avalanche transistor. I need to produce trains of 100 nc square pulses with 1000 ns…
Hi Aaron
Thank you for your reply .
Actually ，the customer had test the LMG1020 , they found it is very hard to get the Input Pulse Width in 1ns , that is why they need us to provide new recommendation , I had provide this reference design to the custo…
Hi Don,
Thanks for your rapid response. I have reviewed TIDA-01573 and discovered two defects in my layout:
1. Layout of power loop is not symmetrical with respect to FET so that I will not achieve half parasitic inductance.
2. Power loop is physically…
Part Number: TDC7201 Other Parts Discussed in Thread: TIDA-01573 , Hi Sir
TIDA-01573 have 5ns pulse width timing capability
May I know the TDC7201 min pulse width timing ? 10nS or less than 10nS ?
Thanks
Hi Jeff,
So what LVDS to CMOS Receiver would you recommend for use with the 1025? Even the http://www.ti.com/product/DS90LV028AQ-Q1 that is mentioned in the TIDA-01573 design guide has a 2.6V (Min), 3.1V (typ) output voltage.
Thanks and Regards,
Mihir
Hi Rocky,
You can think of our drivers as a resistor that can be switched on and off. So, according to Ohms law, yes, current and voltage are related. If the output current is too large for your laser diode, you can put a series resistor to limit the…
Hi Stefan,
Thanks for reaching out on lmg1020.
lmg1020 can be used with 0 ohm resistors to achieve the fastest rise and fall time.
The TIDA report below highlights performance when using the lmg1020 EVM which has 0 ohm gate resistors on OUTH and OUTL…
Hi Koji-san,
Im an apps engineer working with Don on this device and hope to help. Using a current sense resistor may introduce so much inductance it will prevent the current from reaching its peak.
To find the peak current for your laser pulse you need…
Hi Veerababu,
Welcome to e2e, and thanks for your interest in our products!
We have published a data sheet, EVM Users Guide, as well as a TI Design based on the LMG1020:
Perhaps the easiest thing for you to do would be to simulate your use case using…
