Integrated Device Technology Inc. (IDT) has released two clock generators that operate from a single-rail 1.8-V power supply while eliminating the need for multiple discrete timing components. That, according to IDT, reduces board footprint and saves up to 60% in power consumption compared to solutions available in the market.
The San Jose, California-based chipmaker has launched 5L35023 and 5L35021 devices as part of its VersaClock 3S family of low-power, programmable clock generators. These clock generators, like their predecessors, conform to widely used industry standards, including the PCI Express Gen 1/2/3.
IDT is targeting these clock generators at low-power devices such as digital cameras, IP set-top boxes, home entertainment, audio systems, multi-function printers, IoT gateways, small-business storage, medical equipment, and automotive infotainment.
Kris Rausch, vice president and general manager of IDT’s Timing Products Division, outlined the following three features as the most prominent design highlights:
First and foremost, the proactive power-saving function intelligently monitors the power-down status of the downstream clocked component, automatically switching between normal operation and suspend mode.
Second, three individual programmable PLL designs provide a balance between performance; a.k.a. jitter requirement and power consumption. That allows the clock generator to operate within single-digit mA low-power operation or support high-performance requirements such as PCIe Gen 3 with additional power.
Third, dynamic frequency control (DFC), facilitated by one-time programmable (OTP) memory, provides the ability to dynamically switch between up to four pre-programmed frequencies. That enables clock generators to be implemented across multiple designs without electrical re-designs.
IDT also offers the DEV5L35021 and DEV5L35023 development kits to support configuration, verification, and programming of clock generators in a single kit.
