Analog and mixed signal and RF ASIC success factors

An analysis of several success factors in analog/mixed signal/RF ASIC design and manufacture turned up a number of interesting facts. There were many reasons for success that have been already described elsewhere in this blog. However, the interplay of relationships and their impact on the success of ASIC design and development was not touched. Much to our surprise the analysis of over 100 ASIC projects executed in SPG indicated that when significant success was achieved, not only were the obvious success factors present ( see the blog entry) but a key factor was the customer interface. (1) The customer interface was a technical person who was really closely involved in the design from the system side; (2) the technology that was being used to implement the ASIC was an excellent fit to the requirements; (3) the fabrication vendor relationship was strong and close with SPG; then the probability of clear success was over 99% (conservatively). We did not find a single failure in our list of 100 projects when these conditions were also met. ( In addition to the success factors quoted elsewhere in this blog. The very first entry in the blog since its inception). Thus the objective of this entry is to add this success factor to the list. The search for success in the analog/mixed signal/RF ASIC design and development is critical for our success.

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.
General operation.
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.
