The New 1.8V Version of the Leading VersaClock® 3S Programmable Clock Generator Delivers a Compelling Blend of Performance, Power and Flexibility to Consumer and Computing Systems

15 Aug 2017

SAN JOSE, Calif., August 15, 2017 – Integrated Device Technology, Inc. (IDT) (NASDAQ: IDTI) today introduced two new versions of its low-power VersaClock® 3S programmable clock generators. The IDT® 5L35023 and 5L35021 devices provide innovative power-saving features from a single-rail 1.8V power supply while eliminating the need for multiple discrete timing components, and reduce board footprint while saving up to 60% in power consumption versus comparable solutions. Like their predecessors, the new VersaClock® 3S devices meet the performance requirements of widely used standards including PCI Express® Gen 1/2/3. These new devices are ideal for computing systems, digital cameras, IP set-top boxes, home entertainment, audio systems, multi-function printers, IoT gateways, small-business storage, smart devices, medical equipment and automotive infotainment.

“The new VersaClock 3S devices are perfect for customers requiring a single 1.8V power rail to help meet the constraints of today’s low-power compact devices,” said Kris Rausch, vice president and general manager of IDT’s Timing Products Division. “The new chips deliver performance, flexibility and power savings so design teams can hit their performance and power targets using minimal board space.”

Features that enable this optimal combination of performance, power and flexibility include:

  • Proactive Power Saving—intelligently monitors the power down status of the downstream clocked component, automatically switching between normal operation (5-10mA) and suspend mode (<2uA 32.768KHz clock only). This results in energy savings with less design effort.
  • Performance Power Balancing – Three individual programmable PLL designs provide a balance between performance and power consumption. This eases system design trade-offs between jitter requirement and power. The device can operate within single-digit mA low power operation or support high-performance requirements such as PCIe gen 3 with additional power.
  • Dynamic Frequency Control (DFC)—Supported by one-time programmable (OTP) memory, this feature provides the ability to dynamically switch between up to four pre-programmed frequencies, satisfying different operating modes or for use across multiple designs without electrical re-designs.

Available now, the seven-output 5L35023 comes in a 4 x 4 mm QFN package and the five-output 5L35021 comes in a 3 x 3 mm QFN package, both supporting CMOS and LP-HCSL outputs. To accelerate application developments, IDT offers the DEV5L35021 and DEV5L35023 development kits to support configuration, verification, and programming of devices all in one kit.
