Overview

The 2308-1DCG 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 2308-1DCG 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 2308-1DCG enters power down, and the outputs are tri-stated. In this mode, the device will draw less than 25uA. The 2308-1DCG 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 2308-1DCG is characterized for both Industrial and Commercial operation.
