9ZXL1232E - 12-output DB1200ZL Derivative

General Description

The 9ZXL1232E / 9ZXL1252E are second-generation, enhanced-performance DB1200ZL differential buffers.

The parts are pin-compatible upgrades to the 9ZXL1232A and 9ZLX1252A, while offering a much improved phase jitter performance and an SMBus Write Lock feature for increased system security.

Key Features

  • 12 Low-Power (LP) HCSL output pairs (1232E).
  • 12 Low-Power (LP) HCSL output pairs with 85Ω Zout (1252E) Block Diagram VDDR VDDA Features.
  • SMBus write lock feature; increases system.

12-Output DB1200ZL Derivative for PCIe Gen1–4 and UPI with 9ZXL1232E / 9ZXL1252E Write Lock Datasheet Description The 9ZXL1232E / 9ZXL1252E are second-generation, enhanced-performance DB1200ZL differential buffers. The parts are pin-compatible upgrades to the 9ZXL1232A and 9ZLX1252A, while offering a much improved phase jitter performance and an SMBus Write Lock feature for increased system security. A fixed external feedback maintains low drift for critical QPI/UPI applications. The 9ZXL1232E and 9ZXL1252E have an SMBus Write Lockout pin for increased device and system security.
