The failure rate for ICs is defined by: (Number of devices failed/Total number of devices tested)(1/time). The units can be stated as failures per device hour. This is an important parameter and has to be considered as early as possible in the design of the device. A unit called a FIT can also be defined. In this case a FIT = one failure per 1 billion device hours of operation. A FIT can be used to evaluate devices and distributions. The simplest model of failure is given by the parameter called the mean time to failure or MTTF. MTTF = 1/KF. Here KF is simply the failure rate per unit time. This is used in the exponential model which is very popular. The exponential model is simply expressed as: Fail(t) = 1.0 – exp(-KFt). This model is easy to use and calculate and can be used to assess the design of the device based on a failure rate model. Data is usually available from foundries for the use of this model. Please visit our website at http://www.signalpro.biz for more ASIC and module design and manufacturing information. Please contact SPG for detailed information on more extended types of failure expressions and their use in the design of devices. i.e how these failure parameters mesh with design parameters that allow the design to be more robust in terms of MTTF or failure rate.

A high frequency divider from 500 Mhz to % Ghz+
The input interface.
The frequency divider has a differential analog interface. The following parameters apply:
The minimum frequency that can be input is 500 Mhz and the maximum frequency is 6.0 Ghz.
The RF input level is 5 dBm to – 5 dBm. For lower frequencies make sure that the slew rate is
greater than 560 V/us. The input is biased by two 500 Ohm resistors connected to a 1.6V DC bias.
Therefore AC coupling is used at the input. These are two 100pF capacitors.
The output interface.
The output is single ended. The output driver is capable of sourcing and sinking 24 mA. The
equivalent output impedance is 50 Ohm. To avoid reflections it is recommended that the divider
work into a 50 Ohm load.
The inputs are applied to the input SMA I/O. The product will work with both a differential input as
well as a single ended input. However, a differential input works best. The division ratio is applied
to the N1 and N2 control inputs as follows:
N2 N1 Division ratio
0 0 8
0 1 16
1 0 32
1 1 64
The logic levels are:
Logic level Voltage
1 1.4V minimum
0 0.6V maximum
The supply voltage interface.
The operating supply voltage is 3.3V typical. The quiescent (DC) operating supply current is 2 mA.
