The zero delay is achieved by aligning the phase between the ining clock and the output clock, operable within the range of 10 to 133MHz. The IDT23S05 is an 8-pin version of the IDT23S09. IDT23S05 accepts one reference input, and drives out five low skew clocks. The -1H version of this device operates up to 133MHz frequency and has a higher drive than the -1 device. All parts have on-chip PLLs which lock to an input clock on the REF pin. The PLL feedback is on-chip and is obtained from the CLKOUT pad. In the absence of an input clock, the IDT23S05 enters power down. In this mode, the device will draw less than 12µA for mercial Temperature range and less than 25µA for Industrial temperature range, the outputs are tri-stated, and the PLL is not running, resulting in a significant reduction of power. The IDT23S05 is characterized for both Industrial and mercial operation.
