The LTC4307-1 is a 2-wire bus buffer that provides capacitance buffering between input and output. The HDMI specification requires that devices have less than 50pF of input capacitance on their DDC bus lines. The LTC4307-1’s 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 flag 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.
Applications
- HDMI
- 3.3V/5V Level Translation
