WARNING :
This unit contains lethal AC voltages. Disconnect the unit from the AC
supply before removing the cover.
WARNING:
This unit contains dual power supplies. Isolate BOTH power supplied
from AC Power before removing the top cover.
WARNING:
The lightning flash with an arrowhead inside of an equilateral triangle is
intended to alert the user to the presence of un-insulated “dangerous voltage”
within the product s enclosure. The “dangerous voltage” may be of sufficient
magnitude to constitute a risk of electrical shock to people. Do not attempt to
repair the unit without first unplugging it.
CAUTION:
The exclamation point inside of an equilateral triangle is intended to alert the
user to the presence of important operation and maintenance instructions in
the user guide. Only qualified personnel should repair this unit. Several
board assemblies contain static sensitive devices. Appropriate procedures
must be used when handling these board assemblies.

MANUAL P/N 900000178 REV B
1 Introduction
Figure 1. Master Clock System Front View
Brandywine’s M212 Master Clock System represents the next generation of modular
timing systems. Built as a commercial derivative of the highly successful ruggedi ed
Modular Master Clock, the M212 provides assured timing capabilities using
Brandywine’s Timewall™ technology.
At the center of the M212 system is Brandywine’s powerful Master Clock Module
(MCM). The MCM may be synchroni ed by a variety of reference sources and uses the
selected reference to steer an embedded oscillator to provide stable and accurate time
and frequency for the M212. Multiple references can be prioriti ed with automatic
failover. Uniquely, the MCM’s Timewall™ algorithms validate the GPS reference based
upon the inherent stability of the MCM oscillator, providing hardening against possible
GPS spoofing.
Available input reference selections include GPS (both C/A code and SAASM receivers
are supported), IRIG-B, and Have Quick/1PPS. In additional an MCM may be
synchroni ed to up to 2 other M212 chassis using a fiber optic crosslink, this provides
additional resiliency for the M212 time and frequency references.
The standard oscillator in the M212 is a high quality Temperature Compensated Crystal
oscillator, but the M212 optionally can be ordered with other reference oscillator
choices, including Rubidium, Chip Scale Atomic Clock (CSAC) and Oveni ed Oscillator
(OCXO)
The output signals for the M212 are generated by up to 6 Output Signal Modules (OSM),
and are ideal for custom solutions or future expansion. Available modules include NTP,
low-phase-noise frequency, time code modules such as IRIG A, B, G, H, and NASA 36,
BCD, PPS, PPM, Have Quick, serial data (RS232/422) as well as optical crosslink.
The M212 status and control is via front panel display for basic configuration and status,
a secure web browser, and via SNMPv3. Network protocols also fully support privacy
and authentication.

1.1 Master Clock System Basic Concept
The Master Clock System is a master clock that can have its capabilities
defined by the use of standardized modules, allowing custom solutions to be
created from standard hardware.
Through the use of these standardized modules, distributed timing networks
for high accuracy applications may be readily created.
