Renesas Electronics Corporation Application Specific Clock/Timing 9DBL0443ANLGI

The 9DBL0443ANLGI is a low-power, high-performance PCIe fanout buffer designed to support PCIe Gen1 to Gen5 applications. It features four Low-Power HCSL outputs, which help eliminate the need for additional resistors, and provides integrated 100Oc terminations. The device operates in fan-out mode with a frequency range of 1MHz to 200MHz and includes a Loss of Signal (LOS) open-drain output for clock monitoring. The 9DBL0443ANLGI supports extensive SMBus-selectable features for optimization, although the SMBus interface is not required for operation. It operates within a temperature range of -40¬8C to +85¬8C and is available in a compact 5 vó 5 mm 32-VFQFPN package. Typical applications include PCIe riser cards, nVME storage, networking, and industrial control systems. The additive jitter specifications are < 60fs RMS in fanout mode and < 150fs RMS in high-bandwidth zero-delay buffer mode, making it suitable for high-performance clock distribution needs.
