CDCI6214: Current source capability of the device for LVCMOS and LVDS output channel

Pratik Kaul
Prodigy 80 points
Part Number: CDCI6214
Other Parts Discussed in Thread: CDCE6214, LMK3H0102

I want to know how much current can the LVCMOS and LVDS channel outputs can source or sink to an external devices. I couldn't find any parameter for this in the datasheet

    Pratik,

    For all new applications, we recommend using the CDCE6214, as the CDCI6214 is under NRND.

    How many output clocks are required, and for which frequencies? The LMK3H0102 may serve as a more optimal solution for your application: https://www.ti.com/lit/ds/symlink/lmk3h0102.pdf

    For the LVCMOS current sink/source, please refer to the CDCE6214 datasheet. The LVCMOS drivers between the CDCI6214 and the CDCE6214 are the same.

    LVDS drivers source a current, typically around 4.5 mA, across the differential 100-Ohm termination resistor in order to generate the swing.

    Thanks,

    Kadeem
