The DS1088LU-02A+ family of clock generators are designed to provide synthesis of frequencies from 25 MHz to 2000 MHz. It offers the flexibility of programming several common frequency dividers and multipliers using an on-chip microprocessor. This makes it an ideal choice for applications requiring multiple frequency outputs. It also provides the ability to program multiple low-jitter output clocks and can be programmed over an I2C interface.

The DS1088LU-02A+ is suitable for a wide range of clock/timing applications, including broadcast transmission, test instrumentation and military use. It can be used as an oscillator or clock generator, or as a frequency synthesizer capable of producing several frequencies from 25 MHz to 2000 MHz. In addition, the input frequency can be varied up to 25 MHz to cover various clock/timing requirements.

When used as a clock generator, the DS1088LU-02A+ uses a three-stage differential amplifier to generate a low-jitter, fast-switching clock signal. The clock signal is then fed through a programmable frequency divider and multiplier, enabling the output clock rate to be scaled up or down to meet the desired output frequency. The DS1088LU-02A+ also provides output options such as LVDS, LVPECL and differential PECL.

When used as a frequency synthesizer, the DS1088LU-02A+ utilizes a frequency synthesizer architecture that allows the output frequency to be changed continuously while maintaining low jitter and good spectral purity. The frequency synthesizer architecture uses an internal voltage-controlled oscillator (VCO) to generate frequencies in the range of 25 MHz to 2000 MHz, and the output frequency is controlled by an I2C interface. The output of the frequency synthesizer can be programmed to any desired combination of frequency dividers and multipliers, enabling the creation of various frequencies.

The DS1088LU-02A+ has been developed to meet the stringent requirements of modern clock/timing applications. It is designed to provide low-jitter and low-spurious outputs with fast switching, making it well suited for high-performance systems. It also has the flexibility to program several common frequency dividers and multipliers, making it suited for many different types of clock/timing requirements. The DS1088LU-02A+ is therefore an ideal solution for any application requiring synthesized frequencies from 25 MHz to 2000 MHz.
