Microchip Technology ZL40294B 1 to 20 Fanout Buffers

Microchip Technology ZL40294B 1 to 20 Fanout Buffers are ultra-low additive jitter, low-power buffers that are fully compliant with the Intel DB2000QL Standard. The ZL40294B operates from a 3.3V ±5% supply and supports PCIe Gen 5.0 and Gen 6.0 specs.

The Microchip Technology ZL40294B Buffers offer 12kHz to 20MHz additive phase jitter at 32fs, typical at 156.25MHz. The devices operate over an industrial temperature range of -40°C to +85°C. The ZL40294B is ideal for PCI Express generation 1/2/3/4/5/6 clock distribution, servers, storage, and data centers.
