General Description
The 9DB1904 is electrically compatible to the Intel DB1900GS Differential Buffer Specification.This buffer provides 19 output clocks for PCI-Express Gen2 or Intel QPI 6.4GT/s applications.
A differential clock from a CK410B+ main clock generator, such as the ICS932S421 drives the 9DB1904.
Key Features
- Benefits.
- Power up default is all outputs in 1:1 mode/No SMBus programming.
- Spread spectrum compatible/EMI reductions.
- Supports output frequencies up to 400 MHz in bypass mode/flexible fanout buffer.
- 8 Selectable SMBus addresses/no SMBus segmentation required.
- SMBus address determines PLL or Bypass mode/pin savings.
- Dedicated VDDA and CK.
