Q & A
- What is the primary function of the CM2020-01TR?
The CM2020-01TR is designed to provide ESD protection, level shifting, overcurrent output protection, and backdrive protection for HDMI source interfaces.
- What is the package type of the CM2020-01TR?
The CM2020-01TR comes in a 38-pin TSSOP package.
- What are the operating supply voltage ranges for the CM2020-01TR?
The operating supply voltage ranges are 5.0 to 5.5 V for 5V_SUPPLY and 1 to 5.5 V for LV_SUPPLY.
- What is the ESD protection level for the TMDS lines?
The TMDS lines have an ESD protection level of ±8 kV.
- What is the purpose of backdrive protection in the CM2020-01TR?
Backdrive protection prevents reverse current flow into the power supply rail when a powered device is connected to an unpowered device via an HDMI interface, ensuring proper reset and preventing potential damage to the device.
- What are the typical applications for the CM2020-01TR?
The CM2020-01TR is used in PCs, consumer electronics, set top boxes, and DVD/RW players.
