The 9FGV100x programmable PhiClock generator family of devices from Integrated Device Technology (IDT) combine space savings, high performance and low power in a single, easy-to-use solution for next-generation data centre and networking designs based on PCIe Gen4 and future Gen5 requirements.

The devices which are in stock at Mouser Electronics, integrate crystal load capacitors and offer an optional integrated crystal to simplify designs and save board space. The 9FGV100x family provides outstanding PCIe Gen4 performance along with exceptional Ethernet performance with phase jitter as low as 225fs RMS at 156.25MHz (12kHz–20MHz). Extremely low power consumption (as low as 100 mW at 1.8V) also allows placement closer to high-power components, enabling further board space savings.

Additionally, all devices within the 9FGV100x family support the upcoming 25G Extended Data Rate Cache Coherent Interconnect for Accelerators (CCIX) clocking standard.

The 9FGV100x family devices are supported by the 9FGV100x PhiClock PCIe evaluation boards, which enable engineers to conveniently configure and program blank parts of the clock generators for design prototyping.

Each PhiClock PCIe evaluation board is USB powered and comes with a USB cable and IDT’s free Timing Commander software.

After connecting the board to a PC, engineers can use the software to communicate to the board for configuration and frequency validation.

The evaluation boards come equipped with an onboard 25MHz crystal as a reference frequency, two SMA connectors, an I²C interface, and three differential outputs.
