DATASHEET BUFFER CLOCK DRIVER MK3807 01 Description Features The MK3807 01 is a low skew 3 3 V 1 to 10 fanout buffer e Packaged in 20 pin SSOP The large fanout from a single input line reduces loading on the input clock The TTL level outputs reduce noise levels on Available in Pb lead free package the part Typical applications are clock and signal e 1 to 10 fanout buffer distribution e Maximum skew between outputs of same package 0 35 ns Maximum skew between outputs of different packages 0 75 ns e Max propagation delay of 3 8 ns e Operating voltage of 3 3 V Advanced low power CMOS process Industrial temperature range 40 C to 85 C Hysteresis on all inputs Block Diagram gt CLK1 gt gt CLK2 gt gt CLK3 gt gt CLK4 IN gt gt CLKS5 gt CLK6 gt CLK7 gt CLK8 gt CLK9 gt CLK10 IDT ICS BUFFER CLOCK DRIVER 1 MK3807 01 REV D 060407 MK3807 01 BUFFER CLOCK DRIVER FAN OUT BUFFER Pin Assignment IN 1 20 VDD GND 2 19 CLK10 CLK1 3 18 CLK9 VDD 4 17 GND CLK2 5 16 CLK8 GND 6 15 VDD CLK3 7 14 CLK7 VDD 8 13 GND CLK4 9 12 CLK6 GND 10 11 CLK5 20 pin SOIC SSOP TSSOP Pin Descriptions Pin i i Pin Description Number Input Clock input Power Connect to ground Output Clock outpu
3. e Maximum Ratings PCB Layout Recommendations For optimum device performance and lowest output phase noise the following guidelines should be observed 1 The 0 01uF decoupling capacitors should be mounted on the component side of the board as close to the VDD pins as possible No vias should be used between the decoupling capacitors and VDD pins The PCB trace to VDD pin should be kept as short as possible as should the PCB trace to the ground via 2 To minimize EMI the 33Q series termination resistor if needed should be placed close to the clock output Stresses above the ratings listed below can cause permanent damage to the MK3807 01 These ratings which are standard values for IDT 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 Supply Voltage VDD 7V All Inputs and Outputs 0 5 V to VDD 0 5 V Ambient Operating Temperature 40 to 85 C Storage Temperature 65 to 150 C Junction Temperature 125 C Soldering Temperature Recommended Operation Conditions 260 C Ambient Operating Temperature 3 135 3 3 3 465 V Power Supply
