2 The microSync System
2.1 microSync - Brand and Device Type
The registered trademark microSync describes a product family of Meinberg radio clocks for the synchronization
of time and frequency signals in networks and directly connected systems such as signal distributors.
The microSync system is offered in two housing variants (HR = 9.5 inch half-rack chassis, RX = 19 inch
full-rack chassis) with different input and output options. The system name describes the exact hardware con-
figuration.
The available configurations are optimized for the different application areas.

3 microSync System Description
3.1 Device Design, Functions and Area of Application
The microSync product family is a range of high-performance synchronization systems available in 9.5-inch
(Half-Rack) and 19-inch models.
All microSync models offer a wide range of output signals including 1PPS, 10 MHz, IRIG timecodes, pro-
grammable pulses, and fiber optic signals. Furthermore, the Gigabit network ports enable network synchroniza-
tion of NTP clients and PTP slaves.
The microSync systems have an integrated embedded network processor with the sync-optimized firmware
meinbergOS. The firmware supports NTP, as well as all common PTP IEEE 1588 profiles and numerous net-
work protocols for management and monitoring tasks.
The variety of outputs and interfaces allows the use of microSync models in several industries and appli-
cations. Depending on the system requirements, customers can choose from different variants that are best
suited to their needs. The variants are defined via the BNC connectors, which can provide several I/O options.
The following variants are currently available:
10 series
With preconfigured outputs such as Programmable Pulse (TTL), Time Code AM (IRIG, AFNOR) and Frequency
Synthesizer (0.1 Hz to 10 MHz).
30 series
With preconfigured I/Os such as PPS input (TTL), 10 MHz input (sine/TTL), 10 MHz output (TTL) and 10 MHz
sine output.
31 series
With preconfigured I/Os such as PPS input (TTL), 10 MHz input (sine/TTL), Programmable Pulses (TTL).
70 series
With preconfigured I/Os such as Blackburst output, Blackburst input, LTC/GPIO, DARS, Word Clock output
(TTL), programmable pulses (TTL).

3 microSync System Description
3.2 System Variants microSync
The microSync synchronization system is available in different versions. Two housing variants are available
- the space-efficient HR housing (Half Rack, 1HE/9.5 inch built-in housing) and the RX housing variant as
1HE/19 inch built-in rackmount chassis. The RX enclosure offers the option of redundant power with a second
power supply unit as an option. The HR enclosure can be mounted in any 19-inch server cabinet using a 19-inch
mounting bracket. When using multiple HR chassis, it is possible to install two HR devices next to each other
in a 19-inch server rack.
In addition, there are various reference signal options as well as input and output signals optimized for special
applications. A detailed list of all options and their order codes can be found in the following overview.
