ICS650R-14IT

The ICS650R-14IT is a great addition to the Clock/Timing – Clock Generators, PLLs, and Frequency Synthesizers category of products. This fully integrated device from IDT (Integrated Device Technology) combines a fully integrated 14x oscillator, digital PLL, and a host of other features all in a 5x5mm² QFN package. It offers complete timing solutions for a variety of applications, from precision timekeeping to Ethernet communications.

The ICS650R-14IT is a 4th-order delta-sigma PLL (Phase-Locked Loop) with an internal crystal oscillator, and features a 65MHz input clock frequency range with an adjustable 0 to 500KHz frequency range. This allows the user to select between two input clock sources, either a crystal oscillator with an external resistor or an oscillator with an internal clock. This feature-rich part also integrates many control registers, to enable the user to control various aspects of its operation such as frequency, power mode and enable/disable. This product also includes an adjustable clock divider, which allows users to divide the internal clock frequency by 8 or 9.

The device operates from a supply voltage of 1.8V to 3.3V and consumes very low power (1.4mA). It allows for full synchronous EMI optimization with low jitter (1ps) and excellent fractional frequency accuracy (14/16 bits). With its high-performance integration, the ICS650R-14IT enables high-speed switching with minimal CPU power, making it suitable for a wide range of clock & timing applications.

The ICS650R-14IT is well suited for a number of applications, including Ethernet PHYs, SONET/SDH transmitters, high speed clocking, wireless base stations, and test & measurement equipment. Its feature-rich integration and low power operation make it ideal for applications requiring highly precise clock sources. Its low jitter, adjustable frequency ranges, and EMI optimized design make it suitable for components requiring high-speed switching accuracy and reliable transmission.

In conclusion, the ICS650R-14IT from IDT offers a high-performance solution for clock and timing needs. It is a fully integrated, single-package solution with its own integrated crystal oscillator, digital PLL, and adjustable frequency range. This device is ideally suited for Ethernet PHYs, SONET/SDH transmitters, high speed clocking, and wireless base stations due to its low jitter and EMI optimized design. With its wide range of features and low power consumption, the ICS650R-14IT is sure to be a great addition to any Clock/Timing – Clock Generator, PLL, or Frequency Synthesizer.
