TIDA-01634: TIDA-01634

Other Parts Discussed in Thread: LMG1210

As the device is supposed to operate at high frequencies(i.e nearly 50MHz). But the resonance frequency of the input capacitor C3 from Murata is having resonance frequency of less than 10MHz. How it is functional properly in case of high frequencies?

    Hi Ammad,

    Thanks for reaching out about lmg1210.

    1210 can operate up to 50 MHz as long as thermals are ok and the VDD pin is stable with > 300nF of capacitance. Its able to do this due to internal VDD capacitance in which it uses for high frequency source current capability to achieve fast rise and fall times for 50MHz operation. The gate loop inductance of the layout also plays a role to achieve fast switching.

    Please let me know if you have any other questions.

    Thanks,
