Gigabit Multimedia Serial Link with Spread
Spectrum and Full-Duplex Control Channel
MAX9259/MAX9260
______________________________________________________________________________________ 37
Image-Sensing Applications
For image-sensing applications, with remote camera
unit(s), connect the FC to the deserializer (MAX9260)
and set CDS = high for both the MAX9259 and MAX9260.
The MAX9260 powers up normally (SLEEP = 0) and con-
tinuously tries to lock to a valid serial input. Table 14
summarizes the two startup cases, based on the state of
the MAX9259 AUTOS pin.
Case 1: Autostart Mode
After power-up, or when PWDN transitions from low to
high, the MAX9259 locks to a stable PCLKIN and sends
the high-speed data to the MAX9260. The MAX9260
locks to the serial data and outputs the parallel video
data and PCLKOUT.
Case 2: Sleep Mode
After power-up, or when PWDN transitions from low to
high, the MAX9259 starts up in sleep mode. To wake up
the MAX9259, use the FC to send a regular UART frame
containing at least three rising edges (e.g., 0x66), at a
bit rate no greater than 1Mbps. The low-power wake-up
receiver of the MAX9259 detects the wake-up frame over
the reverse control channel and powers up. Reset the
sleep bit (SLEEP = 0) of the MAX9259 using a regular
control-channel write packet to power up the device fully.
Send the sleep bit write packet at least 500Fs after the
wake-up frame. The MAX9259 goes back to sleep mode
if its sleep bit is not cleared within 8ms (typ) after detect-
ing a wake-up frame.
