San Jose, Calif. Integrated Device Technology Inc. (IDT) has extended
its PCI Express (PCIe) Gen2 portfolio of switching solutions with the introduction of
PCIe Gen2-based timing products that include buffers and generators for computing and communications applications.
The Gen 2 timing portfolio contains devices configured with 2 to 19 total differential output and input choices including both differential and crystal inputs. They are also available in a variety of packaging options. The devices provide root-mean-square (rms) phase jitter performance as low as 2 picoseconds, providing a significant performance margin improvement to the PCIe Gen2 specification, said IDT.
The IDT 9FG104D generator can be driven with either a 14.318-MHz or
25-MHz crystal to provide four (4) PCIe Gen2 reference clocks. An eight (8) output version (9FG108D) is available for larger applications such as servers. Both devices are Gen2 compliant, and are backward compatible to the PCIe Gen1 specification. For added flexibility, both devices are completely configurable through hardware pins or through an SMBus interface and offer both spread-spectrum and non-spread-spectrum options.
The IDT 9FG104D is currently available in 28-pin SSOP or TSSOP packages, and the IDT 9FG108D in 48-pin SSOP or TSSOP packaging options. Both devices are available in the -40° to 85°C industrial temperature range.
Pricing: The industrial temperature range IDT 9FG104DGILF in a 28-pin TSSOP is
priced at $1.84 in quantities of 10,000. The equivalent 8-output device (9FG108DGILF) in a 48-pin TSSOP is priced at $2.00 in quantities of 10,000.
