1 / 10 page 1 COMMERCIALANDINDUSTRIALTEMPERATURERANGES IDT23S08E 3.3V ZERO DELAY CLOCK MULTIPLIER FEBRUARY 2004 2004 Integrated Device Technology, Inc. DSC 6499/5 c COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES The IDT logo is a registered trademark of Integrated Device Technology, Inc. FEATURES: • Phase-Lock Loop Clock Distribution for Applications ranging from 10MHz to 200MHz operating frequency • Distributes one clock input to two banks of four outputs • Separate output enable for each output bank • External feedback (FBK) pin is used to synchronize the outputs to the clock input • Output Skew <200 ps • Low jitter <200 ps cycle-to-cycle • 1x, 2x, 4x output options (see table): – IDT23S08E-1 1x – IDT23S08E-2 1x, 2x – IDT23S08E-3 2x, 4x – IDT23S08E-4 2x – IDT23S08E-1H, -2H, and -5H for High Drive • No external RC network required • Operates at 3.3V VDD • Spread spectrum compatible • Available in SOIC and TSSOP packages FUNCTIONAL BLOCK DIAGRAM DESCRIPTION: The IDT23S08E is a high-speed phase-lock loop (PLL) clock multiplier. It isdesignedtoaddresshigh-speedclockdistributionandmultiplicationapplica- tions.Thezerodelayisachievedbyaligningthephasebetweentheincoming clock and the output clock, operable within the range of 10 to 200MHz.

In the absence of an input clock, the IDT23S08E enters power down. In this mode, the device will drawlessthan12µAforCommercialTemperaturerangeandlessthan25µA forIndustrialtemperaturerange,andtheoutputsaretri-stated. The IDT23S08E is available in six unique configurations for both pre- scaling and multiplication of the Input REF Clock. (See available options table.)
