DESCRIPTION:
• Phase-Lock Loop Clock Distribution
• 10MHz to 133MHz operating frequency
• Distributes one clock input to one bank of five outputs
• Zero Input-Output Delay
The IDT23S05T is a high-speed phase-lock loop (PLL) clock buffer,
designedtoaddresshigh-speedclockdistributionapplications. Thezero
delay is achieved by aligning the phase between the incoming clock and
the output clock, operable within the range of 10 to 133MHz.
• Output Skew < 250ps
The IDT23S05T is an 8-pin version of the IDT23S09T. IDT23S05T
acceptsonereferenceinput, anddrivesoutfivelowskewclocks. Allparts
have on-chip PLLs which lock to an input clock on the REF pin. The PLL
feedbackison-chipandisobtainedfromtheCLKOUTpad.Intheabsence
of an input clock, the IDT23S05T enters power down. In this mode, the
devicewilldraw lessthan12μA for Commercial Temperature Range and
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. TheIDT23S05TischaracterizedforbothIndustrialandCommer-
cialoperation.
• Low jitter <200 ps cycle-to-cycle
• No external RC network required
• Operates at 2.5V VDD
• Power down mode
• Spread spectrum compatible
• Available in SOIC package
