Description

The 5T905 2.5V single data rate (SDR) clock buffer is a user-selectable single-ended or differential input to five single-ended outputs buffer built on advanced metal CMOS technology. The SDR clock buffer fanout from a single or differential input to five single-ended outputs reduces the loading on the preceding driver and provides an efficient clock distribution network. The 5T905 can act as a translator from a differential HSTL, eHSTL, 1.8V/2.5V LVTTL, LVEPECL, or single-ended 1.8V/2.5V LVTTL input to HSTL, eHSTL, 1.8V/2.5V LVTTL outputs. Selectable interface is controlled by 3-level input signals that may be hard-wired to appropriate high-mid-low levels. Multiple power and grounds reduce noise.
