8-Output DB800ZL Derivative for PCIe Gen1–4 and UPI with Write Lock
9ZXL0832E / 9ZXL0852E
Datasheet
Description
The 9ZXL0832E / 9ZXL0852E are second-generation, enhanced performance DB800ZL differential buffers. The parts are pin-compatible to the 9ZXL0831A and 9ZXL0851A while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications. The 9ZXL0832E and 9ZXL0852E have an SMBus Write Lockout pin for increased device and system security.
