Overview
The SN65EPT22DGKR is a dual 3.3V LVTTL to LVPECL buffer translator device produced by Texas Instruments. This device is designed to convert low-voltage TTL (LVTTL) or low-voltage CMOS (LVCMOS) signals to differential low-voltage PECL (LVPECL) signals. It is housed in a VSSOP-8 package and is known for its low power consumption and high-speed signal translation capabilities.
