The 5600MSC and 5601MSC Master Sync and Clock Generators are both a broadcast quality master sync pulse generator (SPG) and a master clock. Each provides all of the synchronizing signals needed in a 21st century TV station or post production facility at the same time as solving the problem of locking the in-house master clock system to the master video sync pulse generator.

A high stability, temperature controlled oscillator, provides both the 5600MSC and 5601MSC with better than 1.0x10-8 (or 0.01ppm) frequency reference. The free running drift of this 10MHz reference will be less then 0.1Hz (which amounts to less than1 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. Both the 5600MSC and 5601MSC may also be referenced to an external 5MHz or 10MHz master oscillator if higher stability is required. Both the SPG and the Master Clock section of the 5600MSC or 5601MSC may be referenced to high stability time and frequency standards present in the Global Position System (GPS) by adding the GPS (+GP) option.

The SPG section of both 5600MSC and 5601MSC provides six timeable reference outputs. These six BNC outputs may be configured to provide independently timed color black (black burst) outputs or independently timed HDTV tri-level sync outputs. Each color black output can optionally carry vertical interval time code (VITC) on a user specified set of lines. Additionally, each output can provide 10MHz, 5MHz, PAL Subcarrier, NTSC Subcarrier, 1 PPS, 1/1.001 PPS, 6/1.001 PPS, PAL color frame pulse and 48kHz wordclock

When referenced to the optional GPS receiver, the start of the NTSC four field sequence, or the PAL eight field sequence, will coincide with a specific point in the GPS code. In this way, by referencing all the 5600MSCs (or 5601MSCs) in a system to GPS, they will all be automatically locked to each other. This is ideal for applications requiring remote facility frequency, phase and time locked! GPS heads may be remoted from the unit with standard 50ft. cables included or optional 100ft. & 400ft. weatherproof cables. For remote GPS head requirements of greater than 400ft. or fiber optic isolation, GPS Data Fiber Transmitters & Receivers are also available (7707GPS-DT, 7707GPS-DR).

On the 5600MSC, the master clock section provides a primary longitudinal time code (LTC) output on an XLR connector and a 9-pin D connector, as well as a secondary LTC output available only on the 9-pin D connector. The time code may be set from the front panel or referenced to a number of different sources.On the 5601MSC, the master clock section provides two longitudinal time code (LTC) or optional IRIG outputs on XLR connectors and a 15-pin D connector. The time code may be set from the front panel or referenced to a number of different sources.

Having two LTC outputs provides the ability to drive 24 and 30 Fps, or drop-frame and non-drop frame timecode simultaneously. Time may be externally referenced to GPS or via modem to a high-level time source or extracted from VITC on the reference input. Time derived from such sources can be offset from UTC to a specific time zone as required. When referenced to GPS or by modem (or LTC or IRIG or VITC on 5601MSC), either MSC can provide RFC-1305 compliant NTP via Ethernet, and operates in broadcast and server mode. GPS, NTP and Modem access are all options for both MSCs. Both the 5600MSC and 5601MSC includes a battery backed-up real time clock to maintain its time while power is not applied to the unit.

Input / Output Summary Diagram

On the 5600MSC, an optional word clock output is available (+WC) and also audio word clock may be generated from DARS with 520DARS-W module (Refer to 520DARS-W brochure). For the 5601MSC, a wordclock output is a standard feature. It provides 48kHz wordclock or may be configured as an additional sync output. Also for the 5601MSC, the 10MHz output provides 10MHz or 5MHz, or may be configured as an additional sync output.

For the 5600MSC, there are two test signal generator options available. The STG option provides a composite analog video test signal output, AES and balanced analog audio tone generators and a digital audio reference output (DARS). The STG option also provides two standard definition SDI test signal outputs and two SDI black outputs. The HTG option provides two high definition SDI test signal outputs and two HD SDI black outputs.

For the 5601MSC, there are three test signal generator options available. The SDTG option provides two composite analog video test generators, two AES and one DARS outputs (both balanced and unbalanced), and two balanced analog audio channels. The SDTG option also provides four standard definition SDI test signal generators. The HDTG option includes all features of the SDTG option and adds support for HD formats. The 3GTG option includes all features of the HDTG option and adds support for dual-link and 3G formats. Each test generator has two outputs and a large suite of test signals available. When the 3GTG option is ordered, 3D test signals are also available.

All versions of the 5600MSC / 5601MSC offer a COM port for software upgrades. An optional redundant power supply is also available. For the 5601MSC only, the redundant power supplies are hot-swappable.

Automatic Changeovers

Two 5600MSC units in combination with an Automatic Change Over (model 5600ACO) provide an extra degree of reliability where dual redundant installations are required. The ACO provides relay changeover for the two LTC outputs, the six Sync pulse outputs, the 10MHz reference output, and the GPI/O interface. A serial cable interconnecting the COM ports of the two 5600MSC units guarantees that the configuration and timing of the units are identical so that changeovers are done with minimal disruption of the plant timing reference. The model 5600ACO2 also provides changeover for the optional test generator signals.

In the case of the 5601MSC, two 5601MSC units in combination with an Automatic Change Over (model 5601ACO2) provide an extra degree of reliability. Again, the ACO provides relay changeover for the two LTC outputs, the six sync pulse outputs, the 10MHz reference output, wordclock and the GPI/O interface. The model 5601ACO2 also provides changeover for all the optional test generator signals.
