3.1 General
The LT4670 is a 1U full-rack size sync signal generator that outputs analog video sync signals
and audio word-clock signals. The genlock function allows operation synchronized with input
signals.
The genlock function has a stay-in-sync function that maintains the phase when an error occurs
in the input analog video sync signal. Adding the power option provides redundant operation.
The power supply unit and fan can be replaced without turning off the power of the LT4670
main unit. These features make it possible to configure a highly reliable system.
The LT4670 has six independent standard outputs of the analog sync signal output, digital audio
output, word-clock output, and LTC I/O. Also, options are available for GNSS and PTP
synchronization, arbitrary pattern output using 3G-SDI (4K Quad), HD-SDI, and SD-SDI, etc.
These options are designed to enable the management of the optimal synchronization system
for your application.
3.2 Features
3.2.1 LT4670
Genlock Function
Various output signals can be synchronized by applying NTSC/PAL black burst signals, which are
analog video sync signals, and HDTV tri-level sync signals.
NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field
IDs are also supported.
The 10 MHz CW lock is also supported as a standard feature.
Stay-in-Sync and Slow Lock Functions
A stay-in-sync function is available in case errors occur at the genlock input. In addition, a slow
lock function is available to reduce the shock that occurs when genlock is performed again
based on stay-in-sync. This makes it possible to construct an extremely reliable synchronization
system.
Analog Video Sync Signal Output
Six analog video sync signals can be output. The phase of each output can be adjusted
independently.
NTSC/PAL black burst signal with field reference pulse and NTSC black burst signal with 10 field
IDs are also supported.
Word-Clock Signal Output
The LT4670 can output a 48 kHz word-clock signal synchronized with video signals.
Page 20
3 SPECIFICATIONS
6
AES/EBU Signal Output
This option can output a 48 kHz AES/EBU signal synchronized with video signals. (AES/EBU
connector)
It is also equipped with a AES/EBU signal output compatible with DARS. (SILENCE connector)
CW/1PPS Output
The CW/1PPS output can output 10 MHz CW or 1PPS, whichever is selected.
Time Code I/O
The time code generator can run in free run mode based on internal time information. Based on
the NTP server, LTC, VITC, GNSS (SER01), or PTP (SER03) time information, it can embed the
LTC3 system output and analog video sync signal output in VITC, as well as the SDI (SER02)
output in ATC (LTC/VITC).
LTC I/O
The LTC has three independent outputs for an input. An offset time can be set for each output
with respect to the frame rate and reference time.
Remote Connector
The remote connector can be used to load presets and transmit two alarm outputs.
Inter-instrument Synchronization Control (L-SYNC)
In a redundant system, the time can be synchronized by connecting the main and backup
devices that are synchronized with the same analog video sync signal via L-SYNC.
Real Time Clock
The real time clock is backed up by a battery. There is no need to reset the clock even when the
power is turned off and then back on.
Ethernet
Control is exerted based on the SNMP. When an error is detected, a TRAP is issued. Also, this
instrument can be controlled using the HTTPS (future support), HTTP, and REST-API (future
support).
When connected to an NTP server as an NTP client, the instrument can be used for internal
clock synchronization or as an NTP server.
Preset Memory Function
Up to 10 presets can be saved. Convenient registered presets can be recalled during operation.
The LT4670 can be started with the same settings every time.
Page 21
3 SPECIFICATIONS
7
External Memory Support
The log can be saved and preset data can be written and saved from the panel using USB
memory devices.
Logging Function
The operation status can be logged to internal memory or external memory.
Last Memory Function
When the power is turned on, it starts up with the settings when the power was turned off last
time.
3.2.2 LT4670-SER01 (GNSS)
GNSS Sync
A GNSS antenna can be connected to generate and output signals by locking to the frequency
and clock obtained from the GPS, GLONASS, GALILEO, BDS, and QZSS.
It also features a stay in sync function, which retains the phase and frequency of the output
signal when GNSS signals are lost.
3.2.3 LT4670-SER02 (SDI)
Triple-rate SDI Ready
The SDI signal output supports 3G-SDI (level A and level B), HD-SDI, and SD-SDI. There are
two independent SDI signal output connectors, and different patterns and phases can be set for
each.
Also, two SER02 units can be mounted, and up to four independent SDI signals can be output.
Moreover, adding a 4K option (SER21) supports the 4K 3G-Quad Link.
User Pattern Generation
In addition to internal patterns such as the color bar, SD and HD (2K) user patterns can be
output.
ID Character Overlay
ID characters can be overlaid at any position on the display. In addition, ID characters can be
scrolled horizontally or displayed in a blinking state for checking whether the display has frozen.
Logo Mark Overlay
24-bit full-color bitmap data can be overlaid as a logo mark at any position on the display at a
640 (dots) × 480 (lines) VGA size.
Safety Area Markers
90% and 80% safety area markers can be overlaid on the display. For 3G-SDI and HD-SDI, a
4:3 aspect marker can be overlaid.
Page 22

Pattern Scrolling
This option is equipped with a function for scrolling patterns in eight directions. The moving
speed can be varied.
Moving Box
A moving box can be overlaid on the display. Its color, size, and moving speed can be varied.
Circle
90%, 80%, and 70% circles can be overlaid on the display. Their brightness can be changed,
and they can be displayed in a blinking state.
Time Code
A time code can be overlaid at any position on the display. Its character size and brightness can
be changed.
Audio Embedding
Embedded audio of 16 channels (four channel × four groups) can be embedded. The frequency,
level, and the like can be set for each channel.
Lip Sync Pattern
Lip sync patterns in which the video and audio are synchronized can be output. By using a
waveform monitor that features a lip sync measurement function, such as the Leader’s LV5600,
it is possible to measure the offset between the video and audio in SDI signal transmissions.
3.2.4 LT4670-SER03 (PTP)
PTP Leader Function
This option supports the Precision Time Protocol defined in IEEE1588-2008 and operates as a
PTP grand master. SMPTE2059, AES67, and General profiles are supported. The PTP time
source is obtained from the internal clock, NTP server, GNSS, VITC, or LTC.
PTP Follower Function
When a host PTP grand master is present in the system, this option operates as a PTP follower
and can operate as a PTP leader for lower devices.
Two Independent PTP Ports
Since two PTP engines are mounted, a PTP system can be constructed for each of them as an
independent grand master.
The two engines can be used as followers. (The leader can be selected automatically or
arbitrarily by the user.)
It is also possible to use one engine as a follower and the other as the leader.
10GbE Support
A 10GbE SFP+ module, sold separately, can be used.
Page 23
3 SPECIFICATIONS
9
Local PTP Function
When genlocked to the analog video sync signal or HDTV tri-level sync signal, this function
obtains time information from an external time source, such as a GNSS or NTP server. It can
adjust the time according to the phase information of the genlocked sync signal and redistribute
the PTP time.
3.2.5 LT4670-SER11 (POWER UNIT)
Redundant Power Supply
You can make the power supply redundant.
When errors occur in power supply units, alarms are indicated on the instrument panel. Errors
can also be output as alarms using SNMP.

6.6 L-SYNC
L-SYNC refers to a function whereby, in a redundant system, the primary and backup
instruments, synchronized with the same analog sync signal, can be synchronized in time with
each other.
The following explains how to use it, considering the following system as an example.
Figure 6-3 | L-SYNC
1. Connect the L-SYNC connectors of the LT4670s with an L-SYNC cable.
For the L-SYNC cable, use the LC2186 (sold separately).
2. Apply an analog sync signal to one of the GENLOCK/CW IN connectors of each of the
LT4670 (primary) and the LT4670 (backup).
Apply the same analog sync signal to the primary and backup instruments. Terminate the
unused connector of each of the primary and backup instruments at 75 Ω.
L-SYNC is not supported when the analog sync signal format is 23.98 Hz.
Page 77

3. On each of the LT4670 (primary) and the LT4670 (backup), set REFERENCE SOURCE.
You can set REFERENCE SOURCE with "REFERENCE CONFIG > REFERENCE SOURCE".
Set it to "GENLOCK FMT-AUTO" or "GENLOCK FMT-MANUAL".
When the operation is performed properly, GENLOCK/CW on the front panel lights in green.
4. On the LT4670 (primary), set TIME SOURCE.
You can set TIME SOURCE with "REFERENCE CONFIG > TIME SOURCE". Select one of the
options.
The TIME SOURCE setting of the LT4670 (backup) is fixed to INTERNAL by setting L-SYNC
SETUP to BACKUP in step 5.
When the operation is performed properly, TIME on the front panel lights in green.
5. On each of the LT4670 (primary) and LT4670 (backup), set L-SYNC SETUP.
You can set L-SYNC SETUP with "SYSTEM CONFIG > TIME MANAGEMENT > L-SYNC SETUP".
For the LT4670 (primary), set it to "PRIMARY".
For the LT4670 (backup), set it to "BACKUP".
Subsequently, the time of LT4670 (backup) will be the same as the time set by the LT4670
(primary). When the time of the LT4670 (primary) changes, the time of the LT4670
(backup) will also change accordingly.
