CLOCK CHANNEL
The clock channel incorporates a limiting amplifier, a DC offset correction, and a TMDS driver as shown in
CLOCK CHANNEL SIGNAL DETECT
The DS16EV5110A features a signal detect circuit on the clock channel. The status of the clock signal can be
determined by either reading the Signal Detect bit (SD) in the SMBus registers (see Table 1) or by the state of
the SD pin. A logic High indicates the presence of a signal that has exceeded a specified threshold value (called
SD_ON). A logic Low means that the clock signal has fallen below a threshold value (called SD_OFF). These
values are programmed via the SMBus (Table 1). If not programmed via the SMBus, the thresholds take on the
default values for the SD_OFF and SD_ON values as indicated in Table 4. The Signal Detect threshold values
can be changed through the SMBus. All threshold values specified are DC peak-to-peak differential signals
(positive signal minus negative signal) at the input of the device.
