Management also involves switching of internal clock sources which are not in use in certain
modes of operation; this further reduces the power consumption of the device.
The ZR36504 has two sources of Reset control: The Power-On Reset that comes from a
dedicated input pin RESIN, and the USB-Reset command received from the host
computer. Both reset sources produce a single reset signal inside the ZR36504, which
initializes the ZR36504. It is assumed that a power-on-reset should be applied to the
RESIN pin before any USB transaction is sent to the ZR36504 by host; this is required so
that the Serial-Interface-Engine inside the ZR36504 will be able to receive any valid host
command that will follow (including a USB-Reset command).
The total USB bandwidth that is occupied by the ZR36504 is mainly affected by the
bandwidth of the Video Data Stream (End-Point #2). In order for a host computer, which
initially has a small available bandwidth, not to reject the camera device, the ZR36504 uses
the Alternate-Interface mechanism to enable variable bandwidth. This allows the host
computer to select the highest bit-rate that it can reserve for the Video Stream, starting from
7.5Mb/s down to 0.5Mb/s in 0.5MHz down steps (the selected bit-rate affects the video
quality).
