IDT expands VersaClock 5 family of programmable clock generators with additional PCIe outputs

IDT, the global leader in silicon timing, has expanded its renowned VersaClock® 5 line of programmable clock generators with new versions that simplify the creation of PCI Express® (PCIe®) clocks while still providing the flexible outputs that today’s design engineers have come to appreciate about the company’s family of programmable clock generators.

The new VersaClock 5 programmable clock generators feature dedicated HCSL (LP-HCSL) outputs that reduce both board space as well as bill of materials. It does this by providing an integrated clock generation and distribution solution made especially for PCIe designs.

A bit more specifically, the 5P49V5907 and 5P49V5908 devices feature three outputs capable of generating any frequency up to 350 MHz in configurable output types – LVPECL, LVDS, HCSL or LVCMOS, and additional four or eight LP-HCSL outputs specifically for PCIe clocking. Naturally, they feature the same best-in-class jitter and power performance as the original device, but also worth noting is the family’s superb jitter performance at half the power of its competitors—with a jitter phase of less than 0.7 picoseconds over the full 12 kHz to 20 MHz integration range, the VersaClock 5 programmable clock generators are the perfect choice for the high-end consumer, networking, computing, industrial, and communications markets. 

Highlight features:
• Three programmable outputs with any frequency up to 350 MHz
• LVPECL, LVDS, HCSL, or Dual LVCMOS outputs
• Additional 4/8 copies of low-power HCSL (LP-HCSL) outputs to accommodate PCI Express timing needs
• High Performance:
    – Less than 700 fsec RMS phase jitter
    – Meets the requirements of PCI Express Gen 1/2/3 as well as 1G/10G Ethernet and other high-performance protocols
• Low Power:
    – 35 mA core current consumption
    – Low-power HCSL outputs for PCI Express clocks

And in terms of applications, the VersaClock 5 programmable clock generators can be used with:
• Multi-function printers
• Servers
• Set-top boxes
• Solid-state drives
