Thank you for your patience and kind help!

I am currently designing a driving circuit for a 690nm, 30mW laser diode named HL6738MG. Its operating current is 85mA, and I require a VCO (Voltage-Controlled Oscillator) circuit capable of modulating its frequency at 100MHz. Could you recommend an integrated VCO circuit suitable for this application? Additionally, I plan to use IC-HK and IC-WK for the laser diode and modulation switch circuits, respectively. Are these choices appropriate?

Thank you so much for your help!
