9ZML12x3E Clock Buffers

Renesas Electronics 9ZML12x3E Clock Buffers are second-generation enhanced performance DB1200ZL derivatives. These 9ZML12x3E buffers are pin-compatible with 9ZML1232B and offer improved phase jitter performance. The 9ZML12x3E clock buffers fixed external feedback and maintained low drift for critical QPI/UPI applications. Each input channel has software adjustable input-to-output delay to ease transport delay management for complex server topologies. Features include three selectable SMBus addresses, 100MHz Phase-Locked-Loop (PLL) mode, and software-configurable input-to-output delay lines. These 9ZML1233E and 9ZML1253E buffers offer an SMBus write lockout pin for increased device and system security. Typical applications include servers, storage, networking, and Solid State Drives (SSDs).
