Other Parts Discussed in Thread: AFE4490
Hi there,
on the Evaluationsboard AFE4490 i have two Power Supplies +5V(LED_DRV_SUP and TX_CTRL_SUP) and +3V3(RX_DIG_SUP and RX_ANA_SUP).
On my board there are three Supplies that i can use to drive the Ics:
a- +5V_ANA for LED_DRV_SUP and TX_CTRL_SUP
b- +3V3_ANA for RX_ANA_SUP
c- +3V3_DIG for RX_DIG_SUP
My questions are:
1-Voltage
How do i supply 8x AFE4490 so one cannot influence the other? Ferrite or inductor?
2- Current
In worst case when all 8 ICs run at maximum power consumption, what would be the Current consumption from +5V_ANA, +3V3_ANA and +3V3_DIG?
On the Datasheet it says Input Current momentary at +-50mA, but what if i drive the LEDs with 200mA?
