8-Output DB800ZL PCIe Zero-Delay/Fanout Clock Buffer with SMBus Write Protection

The 9ZXL0852E is a second-generation, enhanced-performance DB800ZL differential buffer. The part is pin-compatible with the 9ZXL0851A while offering a much-improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications. The 9ZXL0852E has an SMBus Write Lockout pin for increased device and system security.
