J14 is a 10 pin ribbon header that provides an external path to monitor the status pins.
J17 is a 10 pin ribbon header that provides an external path to serially communicate with the Any-Frequency
Precision Clock.
To control the Any-Frequency part that is on the Evaluation Board from an external serial port, open the Register
Programmer, connect to the Evaluation Board, go to Options in the top toolbar, and select “Switch To External
Control Mode”.
To control an Any-Frequency part that is on an external target board from the Evaluation Board using its serial port,
tie pin 9 of J17 low so that the on-board Any-Frequency part is constantly being held in reset. This will force it to
disable its SDA_SDO output buffer. This will work only for Evaluation Boards that have Rev C or higher
Any-Frequency parts.
J9 is a three-pin by twenty header that is used to establish input levels for the pin controlled two and three-level
inputs using jumper plugs. It also provides a means of externally driving the two and three-level input signals.
J12 is used to monitor the Any-Frequency Precision Clock voltage.
J1 and J2 are edge mount SMA connectors that are used, if so configured, to supply an external single-ended or
differential reference oscillator.
