OVERVIEW LT4611
DESCRIPTION
This product is a 1U full-rack size sync signal generator that outputs analog video sync signals and audio word-clock signals for broadcast stations. The external sync signal genlock function allows synchronized operation 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. The dual power supply unit provides redundant operation. These features make it possible to configure a highly reliable system.
Further, numerous options are available to allow GPS synchronization and PTP synchronization as well as arbitrary pattern output and digital audio output using 12G-SDI, 3G-SDI, HD-SDI, and SD-SDI. These options are designed to enable the management of the optimal synchronization system for your application.
FEATURES
- LT4611 Main Unit
- 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. - 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
Three analog video sync signals can be output (up to six using an option). 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 LT 4611 can output a 48 kHz word-clock signal synchronized with video signals. - 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 on. - Ethernet
SNMP is supported. When an error is detected, a TRAP is issued. Further, the LT 4611 can be controlled through HTTP. - Preset Memory Function
Up to 10 presets can be saved. Previously registered presets can be recalled during operation. The LT 4611 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 4611 front panel. Errors can also be output as alarms using SNMP.
