ICS2309 3.3 VOLT ZERO DELAY, LOW SKEW BUFFER Description Features The ICS2309 is a low phase noise, high-speed PLL based, low-skew zero delay buffer. Based on ICS’ proprietary low jitter Phase Locked Loop (PLL) techniques, the device provides eight low skew outputs at speeds up to 133 MHz at 3.3 V. The outputs can be generated from the PLL (for zero delay), or directly from the input (for testing), and can be set to tri-state mode or to stop at a low level. The PLL feedback is on-chip and is obtained from the CLKOUT pad. • • • • • Clock outputs from 10 to 133 MHz • • • • • • 5 V tolerant CLKIN The ICS2309 is available in two different versions. The ICS2309-1 is the base part. The ICS2309-1H is a high drive version with faster rise and fall times. Zero input-output delay Eight low skew (<250 ps) outputs Device-to-device skew <700 ps Full CMOS outputs with 25 mA output drive capability at TTL levels Tri-state mode for board-level testing Advanced, low power, sub-micron CMOS process Operating voltage of 3.3 V Industrial temperature range available Packaged in 16-pin SOIC and TSSOP (-1H version only) • Pb (lead) free package available for -1H version (16-pin TSSOP only) Block Diagram VDD 2 PLL CLKIN 0 CLKOUT 1 CLKA1 CLKA2 CLKA3 CLKA4 Control Logic S2, S1 2 CLKB1 CLKB2 CLKB3 CLKB4 GND 1 MDS 2309 D I n t e gra te d C i r c u i t S y s te m s 2 ● 52 5 Ra ce Street, San Jose, CA 9 512 6 Revision 052405 ● tel (408 ) 297 -120 1 ● w ww.i c s t. c om ICS2309 3.3 VOLT ZERO DELAY, LOW SKEW BUFFER Pin Assignment CLKIN 1 16 CLKOUT CLKA1 2 15 CLKA4 CLKA2 3 14 CLKA3 VDD 4 13 VDD GND 5 12 GND CLKB1 6 11 CLKB4 CLKB2 7 10 CLKB3 S2 8 9 S1 16 pin narrow (150 mil) SOIC Output Clock Mode Select Table S2 S1 CLKA1:A4 CLKB1:B4 A & B Source PLL Status 0 0 Tri-state (note 1) Tri-state (note 1) PLL OFF 0 1 Running Tri-state (note 1) PLL ON 1 0 Running Running CLKIN (note 2) OFF 1 1 Running Running PLL ON Note 1.

Decoupling capacitors of 0.01 mF should be connected between VDD and GND on pins 4 and 5, and VDD and GND on pins 13 and 12, as close to the device as possible. A series termination resistor of 33Ω may be used to each clock output pin to reduce reflections. Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS2309. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
