Overview
The SN65EPT22DR 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 LVPECL (Low-Voltage Positive Emitter-Coupled Logic) signals. It is housed in an industry-standard SOIC-8 package and is also available in a TSSOP-8 package option. The SN65EPT22DR supports clock frequencies up to 2.0 GHz and features a typical propagation delay of 420 ps, making it suitable for high-speed data and clock transmission applications.
