Description
Used by PMU to enable/disable power the internal
regulators.
Vih = 1.6V, maximum = 3.6V, internal pull-down 200 Kohm.
Analog input pin.
Crystal oscillator input
Crystal oscillator output
Request signal to host to provide reference clock.
The BCM4319 asserts this signal when the reference clock
(e.g., TCXO) should be enabled.
StateXTAL_PU
XTAL clock neededHIGH
XTAL clock not needed60 KΩ internal pull-down
Add a external pull-down (100 KΩ) to keep the signal
deasserted when the BCM4319 is powered down.
IO supply = VDDIO
Low asserting global chip reset: digital input pin.
