LMH0074: Supply current when no input is present

Part Number: LMH0074
Other Parts Discussed in Thread: LMH0394, LMH0324, LMH0384

Hello, the datasheet shows a graph of supply current versus cable length to be equalized, what supply current range should I expect when no input signal is present?

Thank You

    Hi Martin,
    Current consumption would be the same as long cable.
    In later equalizers like LMH0384 and beyond(LMH0394 or LMH0324) we implemented auto sleep feature. In this mode, device completely powers down signal path and power consumption is minimum - in order of 15mW - if there is no signal or carrier is not detected. If this parameter is very crucial, you may consider these other devices.
