Renesas Electronics 9ZXL0651E/52E Clock Buffers
Renesas Electronics 9ZXL0651E/52E Clock Buffers are the second-generation DB800ZL differential buffers with enhanced performance. The 9ZXL0651E/52E buffers are pin-compatible upgrades to the 9ZXL0651A/52A clock buffers while offering a much-improved phase jitter performance. These 9ZXL0651E/52E clock buffers offer fixed external feedback, which maintains low drift for critical QPI/UPI applications. The 9ZXL0652E clock buffers include an SMBus write lockout pin for increased device and system security. Typical applications include servers, storage, JBOD, and networking.
