Integrated Device Technology (IDT) has expanded its system-on-chip (SoC)-friendly PCI Express (PCIe) timing family with the addition of 1.5 V clock generators and clock multiplexers. The new devices join the previously introduced 1.5 V buffers to provide enterprise-level performance for space- and power-constrained designs. The chips offer up to a 90 percent reduction in power and board space compared to standard 3.3 V current-mode HCSL devices.
“Our PCIe family of 1.5 V generators, buffers and multiplexers deliver industry-leading features that align with our customers’ needs to reduce space and power,” said Dave Shepard, vice president and general manager of IDT’s timing and RF division. “As the latest addition to our broad PCIe timing portfolio, this new family of devices delivers power at less than 30 milliwatts, lowering cost of ownership and virtually eliminating thermal concerns.”
The 9FGU clock generator family delivers two, four, six or eight outputs and is offered with and without internal terminations, giving the designer a choice of a flexible termination, or minimal board space with integrated terminations, for 100 ohm transmission lines. All devices are pin-compatible with IDT’s 1.8 V 9FGV PCIe G123 clock generator family.
The 1.5V 9DMU and pin-compatible 1.8V 9DMV clock multiplexers are two-input devices with either one or four outputs. These clock multiplexers are offered with a choice of external terminations or integrated 100-ohm terminations, and feature a choice of switchover modes. The user can choose between asynchronous switching or synchronous switching modes.
The entire family supports PCIe Gen1, Gen2, and Gen3 (Gen 1-2-3) phase jitter requirements. The chips are ideal for use in DSLR cameras, multi-function printers, solid state drives, vehicle infotainment systems, servers, micro-servers, set-top boxes, PCIe-based storage arrays, and a variety of other PCIe-based applications.
