Integrated Device Technology recently announced it has expanded its system-on-chip (SoC)-friendly PCI Express 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% reduction in power and board space compared to standard 3.3 V current-mode HCSL devices.
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.
