HD74CDCV857A Overview
The HD74CDCV857A is a high-performance, low-skew, low-jitter, phase locked loop clock driver. It is specifically designed for use with DDR (Double Data Rate) synchronous DRAMs.
HD74CDCV857A Key Features
- DDR333 / PC2700-pliant, also meets DDR266 / PC2100 requirement
- Supports 60 MHz to 170 MHz operation range
- Distributes one differential clock input pair to ten differential clock outputs pairs
- Supports spread spectrum clock requirements meeting the PC100 SDRAM registered DIMM
- External feedback pins (FBIN, FBIN) are used to synchronize the outputs to the clock input
- Supports 2.5V analog supply voltage (AVCC), and 2.5 V VDDQ
- No external RC network required
- Sleep mode detection
- 48pin TSSOP (Thin Shrink Small Outline Package)
