BUFFER/CLOCK DRIVER

MK3807-01

Description

Features

The MK3807-01 is a low skew 3.3 V, 1 to 10 fanout buffer.

The large fanout from a single input line reduces loading on

the input clock. The TTL level outputs reduce noise levels on

the part. Typical applications are clock and signal

distribution.

• Packaged in 20-pin SSOP

• Available in Pb (lead) free package

• 1 to 10 fanout buffer

• Maximum skew between outputs of same package 0.35

• Maximum skew between outputs of different packages

0.75 ns

• Max propagation delay of 3.8 ns

• Operating voltage of 3.3 V

• Advanced, low power, CMOS process

• Industrial temperature range -40° C to +85° C

• Hysteresis on all inputs

External Components

PCB Layout Recommendations

The MK3807-01 requires a minimum number of external

components for proper operation.

For optimum device performance and lowest output phase

noise, the following guidelines should be observed.

1) The 0.01µF 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.

Decoupling Capacitors

Decoupling capacitors of 0.01µF must be connected

between VDD and GND, as close to these pins as possible.

For optimum device performance, the decoupling capacitors

should be mounted on the component side of the PCB.

Avoid the use of vias in the decoupling circuit.

2) To minimize EMI, the 33Ω series termination resistor, (if

needed) should be placed close to the clock output.

Series Termination Resistor

When the PCB trace between the clock outputs and the

loads are over 1 inch, series termination should be used. To

series terminate a 50Ω trace (a commonly used trace

impedance) place a 33Ω resistor in series with the clock

line, as close to the clock output pin as possible. The

nominal impedance of the clock output is 20Ω.

Absolute Maximum Ratings

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.
