DisplayPort redriver for video signal conditioning
The SN75DP130SSRGZR is a DisplayPort redriver from Texas Instruments, designed to condition and retransmit differential video signals over longer PCB traces or cable runs. It complies with both DP v1.1a and DP v1.2 standards, making it suitable for video display applications where signal integrity degrades beyond the source driver's reach. Operating from a 3.0V to 3.6V supply rail, the device uses an I²C control interface for configuration of equalization, swing, and pre-emphasis settings. The 48-VQFN (7x7) package with exposed pad provides a low-inductance thermal path to the PCB ground plane, which is critical for maintaining signal quality at multi-gigabit data rates.
Housed in a 48-VFQFN exposed-pad package, the device requires a surface-mount reflow profile consistent with JEDEC J-STD-020 for moisture-sensitive components.
