MPE-V01

Overview

MPE-V01 consist of a mainboard in which is possible to plug up to 5 expansion cards, depending of your needs. It comes in two different version: 19'' chassis and ETSI compatible.
When hosted in the 19'' chassis it is provided with keypad, display and status LEDs for local management. Two hot replaceable PSU (AC or DC) are always presents as well as 2 GbE LAN interfaces for remote management, NTP Server and PTP IEEE 1588 v2 Grandmaster clock.

On the mainboard, in the main section, it's possible to install up to two OCXO (Rubidium as option) and two GNSS receiver (GPS or GLONASS). In order to increase availability and reliability of the system all internal power buses are duplicated. The expansion section it's composed by 5 expansion slots which can host, in any configuration (the unit is capable of automatic inventory), the following modules:


EXP-LPN
expansion module able to provide 4 isolated (80 dB) 10 MHz low noise outputs. The module include an OCXO which permits to maintain outputs active (in holdover) in case of failure of the mainboard OCXOs. Outputs have BNC connectors. Output level is 13 dBm over 50 Ohm.

EXP-10M
expansion module able to provide 4 isolated (80dB) 10 MHz outputs (no low noise). Connectors BNC, output level 13 dBm.

EXP-IB-AM
expansion module able to provide 4 isolated IRIG X AM outputs with BNC connectors.

EXP-IB-DC
expansion module able to provide 4 isolated IRIG X DC outputs with BNC connectors.

EXP-PPS
expansion module able to provide 4 isolated PPS outputs via BNC connectors. Output level TTL /5Vpp – 50 Ohm.

EXP-ETH
expansion module able to provide 2 GbE interfaces and 2 SFP optical ports for NTP/PTP/SyncE. This option can be congured as master or slave. The module can be equipped with its own OCXO.

EXP-GPS
hot replaceable. When present it exclude the on board GPS module if already present on the unit. The module can be equipped with its own OCXO.

EXP-TIME
expansion module providing 4 I/O (congurable as: E1, ToD, PPS).

EXP-MRI
Multi reference Input module. It has 4 autosensing input (Time and/or frequency reference signals). This incoming signals shall synchronize the local oscillator of the system. This module it has change-over function too.
