LT4600A – Compact Sync Generator with 3G Capabilities
The compact, 1U half-rack sized, LT4600A Multiformat Video Generator is applicable to 3G-SDI, HD-SDI and SD-SDI systems. Various output capabilities, such as color bar, SDI check field test pattern, ID characters, logo mark in QVGA size, safety area marker, embedded audio, genlock function for external reference synchronization, and three independent analog black signal systems. Lip Sync is one of the key features included in the product.
- Triple-Rate SDI output
Accepts 3G-SDI (Level A,B) , HD-SDI (include Dual Link) and SD-SDI systems.
Two(2) SDI output can be used independently from each other.
- Superimposing ID characters
The ID characters can be superimposed at any arbitrary position on the screen.
The character blinks to indicate the freeze status.
- Superimposing Logo mark
A logo mark, up to 320(pixels) by 240(lines) in QVGA size can be superimposed at any arbitrary position on the screen.
The logo mark is converted from bitmap to four grade monochrome data.
- Safety-area marker
A 90% and 80% safety-area markers can be superimposed on the screen.
A 4:3 aspect ratio marker can also be superimposed in 3G-SDI or HD-SDI formats.
- Pattern scroll
Simple motion picture mode is provided to scroll the pattern.
- Superimposing embedded audio
The 32 channel of embedded audio signals (link A and link B – each 4ch x 4 groups) for 3G-SDI (level B),
and the 16 channels of embedded audio signals (4ch x 4 groups) can be superimposed.
The frequency and level can be respectively set for each channel.
- Lip Sync test pattern
The LT4600A can output lip sync test pattern in which the video and audio are synchronized.
By using Leader’s LV5770A, you can accurately measure the lip sync of the video and audio on SDI signal.
(3G-SDI Level A/HD-SDI/SD-SDI only)
- Genlock mode
The LT4600A can synchronize with NTSC/PAL black burst signals and HD 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.
Furthermore, Stay-in-Sync function is available in case errors occur at the genlock input.
- Analog black signal output
Three independent analog black signals output systems are provided.
The black burst signal with the same format as the SDI output, or HDTV tri-level sync signal
with the same format of clock frequency can be selected for variable timing.
The NTCS/PAL black burst signal with field reference pulse signal, and NTSC black burst signal with 10-field ID are also applicable.
- Word clock output
The 48 kHz word clock output is provided to synchronize the audio signal.
- AES/EBU digital audio output
AES/EBU digital audio output is provided to synchronize the video signal.
Standard support for SNMP via Ethernet makes it easy to integrate the LT4600A in a network environment.
- USB memory
USB slot in available on the front panel to save and update user data setting.
- Preset function
Up to 10 presets can be saved. You can recall a preset to start the LT4600A with the same settings every time.
- AC Power
AC 90～250V, Power consumption 25W max.
