The IDT23S08E-2DCG is an integrated, low-power, frequency synthesizer and clock generator chip, typically used in high-performance, mixed-signal clock networks. It is designed to synthesize, generate and distribute multiple low-noise clocks with precise frequency control and timing accuracy, making it a very versatile solution for both analog and digital frequency domain applications.

The IDT23S08E-2DCG integrates IDT\'s advanced signal-processing algorithms with a wide frequency-range, high-speed, high accuracy PLL module and has a 2-bit MXM interface. The PLL module is made up of two voltage-controlled oscillators (VCOs) as well as two integrated synchronous buzzers, providing flexibility for precise control of both phase and frequency. The PLL module allows for high-precision spreads for each of the output frequencies and provides selectable spur-eliminating strategies for better performance.

In addition to the PLL module, the IDT23S08E-2DCG also features two independent discrete-time SINC filters for precise frequency channel selection and settling. The design of the SINC filters allows for very low noise and time-domain jitter performance, making it ideal for applications that require high signal-to-noise ratios and precise timing.

The IDT23S08E-2DCG is well suited for a variety of applications including frequency-agile transceivers, wireless communication systems, general-purpose timing, instrumentation, and automotive. It can be used for clock synchronization, clock conversion and clock distribution. The device is used to generate multiple programmable clock outputs from a reference clock input. The clock output frequencies are generated from the reference clock frequency by dividing it by an integer or a fraction.

The reference clock frequency can be buffered using the IDT23S08E-2DCG’s internal reference buffer, which provides a stable, low-noise reference clock signal to ensure high timing accuracy. The device can also output differential clock signals, enabling system designers to minimize noise and interference. Moreover, the IDT23S08E-2DCG supports multiple source standards such as LVCMOS, SSTL, and SSTL13, which makes it convenient for devices that use multiple voltage levels.

In addition, the IDT23S08E-2DCG supports programmable phase-shift resolution, allowing the user to adjust the phase of the clocks more precisely. The phase shift of the PLL is linearly adjustable from 0 to 360°, allowing for the synchronization of clock signals in platforms with multiple clock sources.

The IDT23S08E-2DCG has a best-in-class jitter performance; such features make it an ideal choice for applications that demand high accuracy timing. Furthermore, its integrated power-saving circuitry allows for a total power consumption of up to 150 mW, making it a great choice for applications that require low power consumption.

The IDT23S08E-2DCG is a versatile chip suitable for a wide range of applications requiring precise, low-noise, frequency synthesized and clock generated signals. Its flexibility allows it to be used in a variety of analog and digital applications, while its robust feature-set ensures high performance and accuracy. As such, it is a great choice for both low-power and demanding performance applications, making it a great choice for clock generators, frequency synthesizers and PLLs.
