High De nition Multimedia
Interface (HDMI) Level-
Shifting 2-Wire Bus Buffer
The LTC4307-1 is a 2-wire bus buffer that provides ca-
pacitance buffering between input and output. The HDMI
speci cation requires that devices have less than 50pF of
input capacitance on their DDC bus lines. The LTC4307-1s
capacitance buffering feature, in conjunction with its
sub-10pF data and clock input capacitance, allows HDMI
components to easily meet the 50pF requirement and
tolerate high capacitance on the internal bus.
The LTC4307-1 also provides level-shifting between 3.3V
and 5V systems to allow lower voltage HDMI transmitters,
receivers and EEPROM to interface to the 5V DDC bus.
READY is an open-drain digital output ag that indicates
whether or not the input and output busses are connected
and can interface to the HDMI hot plug detect (HPD) signal.
When driven high, the ENABLE digital input allows the
LTC4307-1 to connect after a stop bit or bus idle. Driving
ENABLE low breaks the connection between the input and
output busses.
