2. SPECIFICATIONS
2.1 General
The LT 4610 is 1U full-rack size sync signal generator that can output triple-rate SDI
(3G-SDI/HD-SDI/SD-SDI) signals. It employs two power supply units for redundant operation
to accommodate power supply failures. The genlock function for external sync signals
enables SDI signals, six sets of analog black sync signals, and audio word-clock signals to be
output synchronously. The genlock function is equipped with a STAY IN SYNC function that
maintains the phase when errors occur in the input signal, making it possible to construct
stable systems. In addition to test pattern output including color bars and SDI check fields,
the LT 4610 can embed ID characters, QVGA logo marks, safety area markers, and
embedded audio in SDI signal output.
2.2 Features
● Triple-rate SDI Ready
SDI signal output supports 3G-SDI (level A and level B), HD-SDI (including dual link), and
SD-SDI. There are two independent outputs of SDI signal output terminals. The pattern
and phase can be set separately for each. (However, only a single output is available for
3G-SDI level B and HD dual link.)
● ID Character Overlay
2. SPECIFICATIONS
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
A logo mark that is 320 (dot) × 240 (line) in size (QVGA size) can be overlaid at any
position on the display. Logo marks are 4-level monochrome data converted from bitmap
data.
● 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.
● Pattern Scrolling
Equipped with a function for scrolling patterns in eight directions. The speed can also be
adjusted.
● Audio Embedding
The LT 4610 can embed 32 channels (link A, link B, 4 channels each × 4 groups) of audio
signals for 3G-SDI level B and 16 channels (4 channels × 4 groups) of audio signals for
3G-SDI level A, HD-SDI, and SD-HDI. The frequency, level, and the like can be set for
each channel.

Page 17
2. SPECIFICATIONS
● Lip Sync Patterns
The LT 4610 can output lip sync patterns in which the video and audio are synchronized. In
combination with a waveform monitor that features a lip sync function, such as the Leader’s
LV 5770A, it possible to accurately measure the offset between the video and audio in SDI
signal transmissions.
● Genlock Function
The LT 4610 can synchronize with NTSC/PAL black burst 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.
A STAY IN SYNC function is available in case errors occur at the genlock input. The LT
4610 also has a slow lock function to reduce the shock that occurs when genlock is
performed again based on STAY IN SYNC.
● Analog Black Sync Signal Output
The LT 4610 is equipped with six independent analog black sync signal outputs, which
makes it possible to vary the timing.
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 LT 4610 can output a 48 kHz word-clock signal synchronized with video signals.
● AES/EBU Signal Output
The LT 4610 can output a 48 kHz AES/EBU signal synchronized with video signals. It is
also equipped with a muted AES/EBU signal output.
● Real Time Clock
The real time clock is backed up with a battery, so time maintained even when the power is
turned off and turned back on. The time can also be maintained even when
GPS signals
cannot be received if the SER01 is installed.
● Ethernet
SNMP is supported as standard. When an error is detected, a TRAP is issued. Further, the
LT 4610 can be controlled through HTTP.
● Preset Memory Function
Up to 10 presets can be saved. Convenient registered presets can be recalled during
operation. The LT 4610 can be started with the same settings every time.
● External Memory Support
Logo data and preset data can be written and saved from the front panel using USB
memory devices.
● Redundant Power Supply
Two power supplies are built in to provide redundancy. When errors occur in power supply
units, alarms are indicated on the LT 4610 panel. Errors can also be output as alarms using
S N M P.

Page 18
2. SPECIFICATIONS
● GPS/TC Option (SER01)
Installation of this option adds (1) a GPS lock function, which locks to the frequency and
time that can be obtained from GPS, (2) 10 MHz CW lock function, and (3) time code
generator function.
In addition to operating in free run mode based on the internal time information, the time
code generator can also output ATC (LTC) and LTC embedded time codes based on GPS,
LTC, and VITC time information.
It also features a holdover function, which retains the phase and frequency of the output
signal when GPS signals or CW signals are lost. Further, when locked to the GPS, the LT
4610 can be used as an NTP server.
● CW I/O (SER01)
The CW I/O connector not only receives 10 MHz CW but also outputs 10 MHz CW or 1PPS,
whichever is selected.
● LTC I/O (SER01)
The LTC I/O connector receives LTC1, outputs LTC 3, and outputs two separate alarms.
