| ICS671-01 ZERO DELAY, LOW SKEW BUFFER AND MULTIPLIER Description The ICS671-01 is a low phase noise, high speed PLL based, 8 output, low skew zero delay buffer and multiplier. Based on ICS' proprietary low jitter Phase Locked Loop (PLL) techniques, the device provides eight low skew outputs at speeds up to 160 MHz at 3.3V. The part includes a bank of six outputs running at either x2 or x4 mode, one output running at either x2, x4, or x4 mode, and one additional output running at either x1, x2, or x4 mode. For normal operation as a zero delay buffer, any output clock is tied to the FBIN pin. ICS manufactures the largest variety of clock generators and buffers and is the largest clock supplier in the world. Features * * * * * * * Packaged in 16 pin SOIC Available in Pb (lead) free package Clock outputs from 5 to 160 MHz Zero input-output delay Integrated x2 or x4 selections, and x5 for CLK7 Eight low-skew (<250 ps) outputs 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 3.3V or 5V Block Diagram VDD 2 CLK1 CLK2 CLK3 CLK4 CLK5 CLK6 CLK7 CLK8 CLKIN FBIN x2, x4, or x5 PLL S1, S0 2 Control Logic 2 GND MDS 671-01 D In te grated Circui t Systems l 1 5 25 Race Stre et, San Jose, CA 9 5126 l Revision 041105 te l (4 08) 297 -1201 l w w w. i c s t . c o m ICS671-01 ZERO DELAY, LOW SKEW BUFFER AND MULTIPLIER Pin Assignment C L K IN CLK1 CLK2 VDD GND CLK3 CLK4 S0 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 F B IN C LK8 C LK7 VDD GND C LK6 C LK5 S1 1 6 p in n a rro w (1 5 0 m il) S O IC Output Clock Mode Select Table S1 0 0 1 1 S0 0 1 0 1 CLK1:6 Tri-state (note 1) x2 (note 2) x2 x4 CLK7 Tri-state (note 1) x5 (note 2) x2 x4 CLK8 Tri-state (note 1) x1 x2 x4 Input Range 5 to 30 MHz 15 to 80 MHz 7.5 to 40 MHz Note 1. Outputs are in high impedence state Note 2: In S1:S0 = 01 Mode, only the x1 output on CLK 8 will be zero delay. The x2 and x5 outputs can power-up in different states so the skew relationship is not defined.

Decoupling capacitors of 0.01mF 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 33 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 ICS671-01. 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.
