9ZXL1530D
Description
The 9ZXL1530D / 9ZXL1550D are second-generation enhanced-performance DB1900Z-derivative differential buffers. The parts are pin-patible upgrades to the 9ZXL1530B and 9ZXL1550B, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications. In fanout mode, the devices meet the DB2000Q additive phase jitter specification.
