The 9ZML1253E is a second-generation enhanced performance DB1200ZL derivative. The part is a pin-compatible upgrade to the 9ZML1232B while offering a much-improved phase jitter performance. Fixed external feedback maintains low drift for critical QPI/UPI applications, while each input channel has software adjustable input-to-output delay to ease transport delay management for today's more complex server topologies. The 9ZML1253E has an SMBus Write Lockout pin for increased device and system security.
