1. OVERVIEW
Figure 1-1: Front View of the 5700MSC-IP
The 5700MSC-IP is an IP Network Grand Master Clock and a Video Master Sync Generator both
referenced to GNSS (Global Navigation Satellite System (GPS and/or GLONASS)). The system
features two 1Gb/s Ethernet, two 10Gb/s Ethernet SFP ports, 6 fully timeable sync outputs, 4 SDI
outputs, and a loop thru reference input. For those hybrid plants where LTC outputs and AES/analog
audio test generator signals required, an optional (+AUX) expansion module is available.
This combo IP Network Grand Master Clock and Master Sync Generator is ideal for timing today’s IP
based video broadcast, production, and distribution facilities. It provides all the future timing needs of
an IP based plant while providing precision reference to any baseband SDI/Analog systems.
The test generator option(s) provide several test generator signals which are available on the 4 SDI
(SD/HD/3Gbps) outputs as well as over the 10Gb/s Ethernet IP outputs (10Gb/s Ethernet SFP’s are
optional). There are 10 independent test signal generators when a test generator option is ordered,
any can be routed to the 10Gb/s Ethernet outputs, or the SDI outputs (4 generators may be combined
to form a 4K signal generator).
As for IP timing formats, the 5700MSC-IP has been designed to be enterprise class, handling all
current IP timing needs with the horsepower to address the future. It supports NTP, PTP-IEEE1588,
MASTER PCR, AVB-IEEE802.1AS, AES67 profile and SMPTE 2059-2. IP networking for live
production and broadcast environments have very specific needs and requirements that typically
involve deterministic flows, high bandwidth, and an SDN based network design. The 5700MSC-IP can
be used to design a robust, safe, and deterministic timing system for any IP Network or Hybrid
IP/Baseband Video system. The product has been designed to handle timing requirements of several
thousands of PTP clients. The 5700MSC-IP has two 10Gb/s Ethernet ports as well as two 1Gb/s
Ethernet ports that can be configured to provide and distribute any of the timing protocols described
above.
This 5700MSC-IP is delivered with a GNSS head capable of receiving GPS and GLONASS satellite
constellation signals and complete with a 50ft cable for remote mounting. (100ft, 400ft and fiber optic
extension options are available for longer cable lengths).
A high stability, temperature controlled oscillator provides the 5700MSC-IP with better than 1.0x10-8
(or 0.01ppm) frequency reference. The free running drift of this 10MHz reference will be less than
0.1Hz (which amounts to less than one millisecond time drift per day). This guarantees that any
frequency drift, with time and temperature, will be within the tolerances expected from the best SPGs
or master clocks available in the industry. Note that the provided GNSS head capable of receiving
GPS and GLONASS satellite constellation signals is required for PTP, AVB PCR, or 2059-2 timing
protocols to be hosted by the system. The 5700MSC-IP can also produce PTP, AVB, PCR or 2059-2
timing protocols when using a PTP reference of suitable quality.
