IDT Introduces First Spread Injection PLL Buffering Solution
New Device Adds Spread Spectrum to Systems Needing EMI Reduction Without Replacing Clock Source
SAN JOSE, Calif., September 28, 2009 – IDT® (Integrated Device Technology, Inc.; NASDAQ: IDTI), a leading provider of essential mixed signal semiconductor solutions that enrich the digital media experience, today announced the industry’s first spread injection buffer — the IDT spread injection PLL. This differential buffer is designed to add spread spectrum, which reduces electromagnetic interference (EMI) in a device, to systems that use a non-spreading clock source, helping improve signal quality and performance in the end device. The IDT spread injection PLL can add spread spectrum without replacing the original clock source in systems, providing design flexibility while saving design time.
Uniquely, the IDT 9DS800 device does not use a crystal oscillator to generate spread. Instead, the IDT spread injection PLL takes in a 100MHz differential clock and adds spread to it to reduce EMI, thereby improving signal integrity. Then, the device makes eight copies of the 100MHz differential clock with spread added for use throughout the system, helping further reduce EMI and improve signal integrity. In addition, the IDT 9DS800 allows the user to turn spread on and off and to select the amount of spread needed via pin selection or the SMBus interface, allowing for greater design flexibility.
Rather than replace a non-spreading clock source with a pin-compatible spread spectrum clock source, the IDT 9DS800 can simply be added to the board, reducing the design time. Since the IDT 9DS800 is footprint compatible with the popular IDT 9DB803 PCI Express® (PCIe®) Gen 2 buffer, spread can be added without board redesigns or shielding, saving design time.
The IDT spread injection PLL is PCI Express Gen 2 compliant and can be used in any general purpose design where spread spectrum needs to be added to a 100MHz differential clock source.
