DESCRIPTION

Fig. 1 Functional Block Diagram

The ASNT_501 system on board functions as a multi-purpose divider for test, microwave, and communication
applications. The selectable divide output can be operated single-ended or differentially. A secondary fixed
divide-by-8 output can also be used single-ended or differentially. The high-speed clock input is AC coupledwith a K-type Southwest connector MFG PN: 1092-03A-5. The clock outputs are AC coupled with Emerson
SMA connectors MFG PN: 142-0761-881. Power is supplied through a two pin MOLEX connector P/N: 39-281023.

APPLICATIONSThe ASNT_501 divider can be used as a prescaler to extend the useful frequency range for triggering. The
second fixed divide-by-8 output can be used to synchronize other devices. The divider can also be used as aprescaler for PLL’s or frequency counters.

DIVIDE RATIO CONTROLThe divide by (2-to-1024) output has been configured to divide the input frequency ratio from 2 to 1024. The
following equation {Div/ output n = 4m}, where m is an integer from 1 to 256 which provides all possible
divide ratios. The divide ratio control contains 8 switches which represent 8 bits. The LSB starts at SW1 andthe MSB ends at SW8. The binary value of zero gives a decimal m value of 256. Ascending binary values
increase the decimal value m. Table 1 shows values of m with their corresponding binary representation.
