IDT23S08

    The IDT23S08 is a high-speed phase-lock loop (PLL) clock multiplier. It is designed to address high-speed clock distribution and multiplication applications. The zero delay is achieved by aligning the phase between the incoming clock and the output clock, operable within the range of 10 to 133MHz.

    The IDT23S08 has two banks of four outputs each that are controlled via two select addresses. By proper selection of input addresses, both banks can be put in tri-state mode. In test mode, the PLL is turned off, and the input clock directly drives the outputs for system testing purposes. In the absence of an Input clock, the IDT23S08 enters power down. In this mode, the device will draw less than 12µA for Commercial Temperature range and less than 25µA for Industrial temperature range, and the outputs are tri-stated.

    The IDT23S08 is available in six unique configurations for both prescaling and multiplication of the Input REF Clock. (See available options table.)

    The PLL is closed externally to provide more flexibility by allowing the user to control the delay between the input clock and the outputs.

    The IDT23S08 is characterized for both Industrial and Commercial operation.
