Timing chips expand PCIe clock generation options
VersaClock 5 programmable clock generators are available to simplify the creation of PCI Express clocks while providing flexible outputs. They have dedicated low-power HCSL (LP-HCSL) outputs that reduce board space and bill of materials by providing an integrated clock generation and distribution solution for PCIe designs. The 5P49V5907 and 5P49V5908 devices have three outputs that can generate any frequency up to 350 MHz in various output types, and an additional four or eight LP-HCSL outputs specifically for PCIe clocking. They possess the same jitter and power performance as the original 5P49V5901 device.
VersaClock 5 programmable timing devices maintain jitter performance at half the power of competing devices, with RMS phase jitter of less than 0.7 psec over the full 12 kHz to 20 MHz integration range. 5P49V5907 and 5P49V5908 cost $5.50 and $6.50 (1000) respectively.
