CDCM7005HFG/EM is a member of Integrated Device Technology’s family of Clock Generators, PLLs, Frequency Synthesizers. It is based on IDT\'s proprietary Digital Phase Lock Loop (DPLL) technology. It is designed to provide a low-cost, highly programmable frequency synthesis solution to system level timing solutions. In addition to its frequency synthesis capabilities, the device also provides a highly flexible and programmable clock distribution and control block.

The main application of the CDCM7005HFG/EM is in consumer electronic devices. It is suitable for a broad range of consumer electronic products, including digital audio, digital multimedia, digital video, and consumer digital photography. It is also used in automotive and industrial applications, including automotive infotainment and industrial displays.

The working principle of CDCM7005HFG/EM is based on its frequency synthesis capabilities. This device is capable of generating up to 12 different frequencies ranging from 4 MHz to 400 MHz. The device is also capable of generating output clocks with different formats, including LVCMOS, LVDS, and HCSL. In addition, it provides a highly accurate frequency and phase synthesizer, with an operating range from 0.25 Hz to 16 MHz.

The device utilizes a patented dual loop approach to provide highly accurate frequency synthesis, eliminating the need for external components for phase and frequency alignment. The process begins by generating a reference clock at an adjustable frequency. This reference clock is used as the input for a Phase Locked Loop (PLL) circuit, which then generates the output clock at the desired frequency. The phase and frequency information from the PLL is then passed to the Digital Frequency Synthesizer (DFS) block, which is responsible for producing a highly accurate output clock.

Finally, the output of the DFS block is then passed to the output driver block. This block is responsible for producing the desired output format and amplifying the output signal. Once the output driver block has produced the desired output, it is passed through a programmable gain control block, allowing the user to control the amplitude of the output signal.

This device is an ideal solution for consumer electronic applications requiring precise timing, frequency synthesis, and clock distribution. The programmability and high level of accuracy makes this device suitable for a wide range of applications. Its low cost, combined with its easy to use programming interface, make it an ideal choice for designers who need a low cost, high performance, and reliable frequency synthesis solution.
