11.8.20 CPE and BPE Output Modules (Frontend - Backend, Eurocard)
Configurable Port Expander / Backplane Port Expander
The standard output signals like pulses (1PPS, 1PPM and freely programmable pulses) and frequencies (10MHz,
2.048MHz, frequency synthesizer 1kHz-10MHz) are provided by two versatile I/O cards named BPE and CPE.
Both of these two modules have been designed to cover a wide range of interface and signal/protocol require-
ments. They feature a two-tier architecture with a back-end and front-end.
The back-end is responsible for internally routing the backplane IMS synchronization signals (in case of the
BPE) or for autonomously generating a wide range of different signals by using a microprocessor (on a CPE).
The front-end makes a selection of the signals available on physical connectors.
