Power Up Timing - Nokia RH-27 Series Technical Documentation Manual

RH-27
Troubleshooting - Baseband
which indicates if the data is the last byte from image frame. When a byte is the last
byte of an image frame from the camera, the TxEnd-bit is set high ('1'). Otherwise the
TxEnd-bit is set low ('0') by the camera. The camera can interrupt the baseband by driv-
ing TxDa low for at least one ExtClk cycle when not transferring an image. The interrupt
is initiated by the falling edge of the signal.
ExtClk is external system clock for the camera module. The clock may be AC or DC cou-
pled. Four fixed frequencies are available (8.4, 9.6, 9.72,13, and 16.8 MHz each within
+/-100kHz).
VIO is a regulated 1.8V nominal I/O logic supply for the camera module.
VCtrl is a control signal to place the camera and HWA in their lowest power consumption
modes. It must be permissible to pull this signal up if this functionality is not required.
VANA is a regulated 2.78V nominal voltage from the engine to the camera module.
GND is system GND for camera module.
