PCIe clock buffers
26 June 2019, Analogue, Mixed Signal, LSI

Microchip Technology announced four new 20-output differential clock buffers that exceed PCIe (PCI Express) Gen 5 jitter standards for next-generation data centre applications. The ZL40292 (85 termination) and ZL40293 (100 termination) are specifically designed to meet the new DB2000Q specification, while the ZL40294 (85 termination) and ZL40295 (100 termination) are designed to meet the DB2000QL industry standard. These new devices also meet PCIe Gen 1, 2, 3 and 4 specifications.

Each buffer is an ideal complement to chipsets where distributed clocks are required across several peripheral components, such as central processing units (CPUs), field programmable gate arrays (FPGAs) and physical layers (PHYs) in data centre servers and storage devices, along with many other PCIe applications.

The devices’ low additive jitter of ­approximately 20 femtoseconds far exceeds the DB2000Q/QL specification of 80 femtoseconds. This gives designers large margins to meet tight timing budgets while achieving increasing data rates. These devices will minimise jitter when distributing clocks to up to 20 outputs, thereby maintaining the integrity and quality of the clock signal through the buffer.

The new buffers achieve low power dissipation and contribute significant savings to power budgets by using low-power high-speed current steering logic (LP-HCSL). Compared to standard HCSL, LP-HCSL consumes one third of the power, leading to a significant decrease in power consumption. This feature also gives customers the ability to drive longer traces on their board, improving signal routing while reducing components and board space. The ZL40292, for example, can eliminate up to 80 termination ­resistors (four per output) compared to traditional HCSL buffers.
