MiCLK
1588 Grandmaster on an SFP with Built-in GNSS
• Fully-featured Primary Reference Time Clock (PRTC) and IEEE 1588-2008 (PTP)
Grandmaster
• Built-in GNSS receiver
• Miniature pluggable device fits in any standard SFP port
• Ideal for 4G small cell deployments
• Cost-effective upgrade solution for legacy 2G/3G networks
MiCLK® offers a cost-effective migration
path for providing robust synchronization
near the network edge. It enables flexible
deployment and easy integration into
existing networks. The cutting-edge
embedded GNSS receiver features
excellent time accuracy even under
challenging deployment scenarios such as
building walls and urban canyons that are
typical for small-cells installations. Design,
and timing redundancy techniques,
provide resiliency against local GNSS
outage.
MiCLK supports both Layer-2 and Layer-3
PTP distribution in unicast and multicast
modes.
FULL-FEATURED PTP GRANDMASTER
MiCLK distributes frequency and time
simultaneously, according to both ITU-T
G.8265.1 (IP/unicast) and ITU-T G.8275.1
(L2/multicast), and G.8275.2 (IP/unicast)
PTP telecom profiles. This is especially
effective in hybrid cellular environments
that comprise co-located 3G/4G base
station technologies. When working in
ITU-T G.8265.1 or G.8275.2 mode, MiCLK
supports up to 64 simultaneous slaves
(symmetric 128 packets/second).
PRIMARY REFERENCE TIME CLOCK
MiCLK is used as an ITU-T G.8272 Primary
Reference Time Clock (PRTC), providing
information on GNSS time and frequency
information to the network, by supplying
a Sync-E distribution chain (Sync-E
Ethernet SSM messages) and using its
1-PPS external interface output.
RESILIENCY
To achieve network-wide resiliency an
operator may allow two or more PTP flows
to reach every slave (base station), it is
the slave who selects the best master
available.
One option is to install two or more MiCLK
units in geographically separated network
elements located in the same backhaul
network section.
Alternatively, two MiCLK units can be
plugged into the same router/switch
(connected to the same GNSS antenna via
a standard passive RF splitter).
An operator may choose a combination of
both resiliency types.
MiCLK supports multiple GNSS backup
schemes. If the underlying network
already supports Sync-E, MiCLK exploits
the incoming Sync-E reference to maintain
its accurate time during a GNSS outage.
Another resiliency option is the Assisted
Partial Timing Support (APTS). MiCLK
simultaneously functions as a
Grandmaster (GM) and a slave of 1588.
The slave inside MiCLK synchronizes to an
incoming PTP stream received from the
central GM. During a GNSS outage, MiCLK
recovers the frequency from the central
GM to maintain its accurate time.
MARKET SEGMENTS AND
APPLICATIONS
Deployment scenarios include future 4G
mobile networks, such as LTE and LTE-A,
with a particular focus on small cell
applications. Furthermore, support of
simultaneous L2/L3 PTP distribution also
provides a cost-effective upgrade solution
for legacy 2G and 3G networks by
supporting SDH replacement scenarios.
MiCLK’s preferred deployment location is
versatile. Due to its cost-effectiveness,
MiCLK can be widely placed close to the
base stations in order to reduce packet
delay variation and asymmetry.
Furthermore, MiCLK saves CAPEX by
adding timing capabilities to existing
aggregation points, servicing dozens of
base stations.
