Microsemi / Microchip ZL40292 Clock Fanout Buffer
Microsemi / Microchip ZL40292 Clock Fanout Buffer is a high-performance, ultra-low jitter device fully compliant with the Intel® DB2000Q Specification. The ZL40292 offers 20 Low-Power Push-Pull HCSL (High-Speed Current Steering Logic) PCIe Outputs and supports clock frequencies up to 250MHz. The ZL40292 Buffer also features an integrated Low Drop Out (LDO) Voltage regulator, which provides superior power supply noise rejection. The device supports a 3.3V power supply and offers a maximum output-to-output skew of 50ps.
Microsemi / Microchip ZL40292 Clock Fanout Buffer is offered in a 10mm x 10mm, 72-pin Quad Flat No-lead (QFN) package. The device's operation is guaranteed over the -40°C to +85°C industrial temperature range.
