9ZXL1251E
9ZXL1251E is 12-Output DB1200ZL manufactured by IDT.
- Part of the 9ZXL1231E comparator family.
- Part of the 9ZXL1231E comparator family.
Description
The 9ZXL1231E / 9ZXL1251E are second-generation, enhanced performance DB1200ZL differential buffers. The parts are pin-patible upgrades to the 9ZXL1231A and 9ZXL1251A, while offering much improved phase jitter performance and increased system security features
. A fixed external feedback maintains low drift for critical QPI/UPI applications.
