TMDS351PAGR

Texas Instruments · Interface - Specialized · TQFP-64(10x10)

TMDS351PAGR from Texas Instruments, in a TQFP-64(10x10). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	SDA3	bidirectional	Source port 3 DDC I2C data line; DDC I/O input voltage is limited to GND to VDD.
2	SCL3	bidirectional	Source port 3 DDC I2C clock line; DDC I/O input voltage is limited to GND to VDD.
3	GND	power_in	Ground reference for the device.
4	B31	input	Source port 3 TMDS negative input.
5	A31	input	Source port 3 TMDS positive input.
6	VCC	power_in	3.3-V TMDS supply; recommended range is 3 V to 3.6 V.
7	B32	input	Source port 3 TMDS negative input.
