OUTPUT LEVEL CONTROL
The output amplitude of the TMDS drivers for both the data channels and the clock channel can be controlled via
the SMBus (see Table 1). The default output level is 1000mV p-p. The following Table presents the output level
values supported:

AUTOMATIC ENABLE FEATURE
It may be desired for the DS16EV5110A to be configured to automatically enter STANDBY mode if no clock
signal is present. STANDBY mode can be implemented by connecting the Signal Detect (SD) pin to the external
(LVCMOS) Enable (EN) pin. In order for this option to function properly, REG07[0] should be set to a “0” (default
value). If the clock signal applied to the clock channel input swings above the SD_ON threshold specified in the
threshold register via the SMBus, then the SD pin is asserted High. If the SD pin is connected to the EN pin, this
will enable the equalizer, limiting amplifier, and output buffer on the data channels and the limiting amplifier and
output buffer on the clock channel; thus the DS16EV5110A will automatically enter the ACTIVE state. If the clock
signal present falls below SD_OFF threshold specified in the threshold register, then the SD pin will be asserted
Low, causing the aforementioned blocks to be placed in the STANDBY state.
