9ZXL1951D
9ZXL1951D is 19-Output DB1900ZL Derivative manufactured by IDT.
Description
The 9ZXL1951D is a second-generation, enhanced performance DB1900ZL derivative buffer. The part is a pin-patible upgrade to the 9ZXL1951A, offering a much improved phase jitter performance. It has 8 OE# pins that can be configured via SMBus to control up to 16 of the device's 19 outputs, and is packaged in a 6 x 6 mm QFN package for maximum space savings. A fixed external feedback maintains low drift for critical QPI/UPI applications.
