APPLICATIONS INFORMATION
Figure 3. The LTC4307-1 in HDMI Capacitance Buffering Application
Figure 4. The LTC4307-1 in a Level Shifting and Capacitance Buffering HDMI Application with Backup 3.3V
Figure 4 shows the LTC4307-1 being used for capacitance
buffering and 5V to 3.3V level shifting. In this application,
the EEPROM is powered by a backup 3.3V supply that is
available when the component is turned off. The EDID in
the EEPROM should be available for reading even when
a component’s power is off.
Although the applications shown in this section are for
HDMI receive channels, the LTC4307-1 can also be used
in HDMI transmit channels with equal success as shown
in the Typical Application on the last page of this data
sheet.
