| Part Number | HD74CDC2509B |
| Manufacturer | Hitachi Semiconductor |
| Description | The HD74CDC2509B is a high-performance, low-skew, low-jitter, phase-lock loop clock driver. It uses a phase-lock loop (PLL) to precisely align, in both frequency and phase, the feedback (FBOUT) output... |
| Features |
• • • • • Meets “PC SDRAM registered DIMM design support document, Rev. 1.2” Phase-lock loop clock distribution for synchronous DRAM applications External feedback (FBIN) pin is used to synchronize the outputs to the clock input No external RC network required Support spread spectrum clock (SSC) synthesizers Note: Only by a change of a suffix (A to B) for standardization, there isn’t any change of the product.
