and automatically select that reference. It also has the option of manually selecting the reference that should be
used. The order or priority of the reference clocks are shown below.
External Reference Clock Sources and Frequencies Supported
Reference Source Clock
(clocks shown in accending order
with highest priority clock first)
Clock Frequencies
Supported
CP2 Link1 20 MHz
CP2 Link2 20 MHz
External Reference 5 MHz, 10 MHz, 20 MHz, and 5
MHz / 1 PPS
OCXO Reference 10 MHz or 20 MHz
Front Panel 5 MHz or 10 MHz
1 PPS Sources
The table below shows the possible 1 PPS sources and their priority levels. Each source can be manually or
automatically selected based on the configuation of the STIC FPGA. While both CP2 links have an imbedded
1PPS signal, the Host CPLD will select which CP2 1 PPS signal gets sent to the FPGA. Thus there is only one
CP2 1 PPS signal to the FPGA.

External Interfaces
RS-232 Port
This Async port is used to hook up to a dial up modem, MOSCAD, and as the zone link for a Trunking IR system.
This port can also be configured for asyncronous operation. This port interfaces to SCC2 of the MPC8250.
