Product number: TL7055-PK

The TL7055 is a small form factor full HD 3G-SDI / HD-SDI plus analog YsPbPr output video transmitter for block cameras from AIVION. Camera LVDS video input signals are demultiplexed, processed and encoded. 3G/HD-SDI Video is output over a MCX connector. Analog YsPbPr Video is output over a 8pin board to wire connector.

TL7055 PCB Outline


Board Operation: TL7055

TL7055 operates fully automatic with respect to outputting video over SDI and analog YsPbPr. Sync is provided as SMPTE compliant tri level sync on the Y signal.
The output video standard is defined by the video standard of the video signal source. TL7055 locks automatically to the signal source as long as the provided video format is supported (see page 1 for supported video modes).
The video source is typically a block type camera or equivalent device providing digital 4:2:2/8bit per component video as
7:1 serialized data stream. This data stream is transmittted over 4 (single mode) or 8 (dual mode) LVDS channels from the video source and is received and demultiplexed by the video processor on TL7055. In all cases embedded sync (SAV/EAV) codes must be present in the LVDS data streams. In case of dual mode it must be present in both channels.
In case of block type cameras, the respective camera register must be set correctly for single or dual LVDS output mode.
TL7055 requires dual LVDS mode in case of 1080p60, 1080p59.94 or 1080p50 video. For all other video standards single LVDS must be choosen in the camera.
When the video standard and/or the LVDS output mode is changed in the camera, TL7055 must get a power reset cycle to lock on the new system settings. Such a reset cycle can be achieved by switching power off and on again or by applying a reset to pin 5 of J2 (see page 2 for details).
The camera (or video source) can be controlled over a transparent, full duplex data channel. TL7055 does not process or change any control data. The full duplex data channel can be accessed by the RS232 interface of TL7055.

Test Pattern Generator (TPG) mode:

TL7055 has an integrated test pattern generator which can be activated and deactivated by VISCA commands. Such settings are not permanently stored. That means every time power is switched off and on again, the TPG is not activated as default.
TPG can be activated even when no camera or video source is present. TPG starts always with providing a 100% color bar pattern in 1080p60 mode. This can be changed by VISCA commands afterwards.
The TPG is seen as a VISCA device using highest VISCA address 0x87. It is required to use a baud rate of 9600bps with 8N1 serial data configuration for TPG control.
The following VISCA commands are available for TPG control (all codes as hex values):
TPG activation:
87 01 00 24 01 08 0A FF
TPG deactivation:
87 01 00 24 01 08 06 FF
TPG pattern type 100% color bar:
87 01 00 24 04 00 04 FF
TPG pattern type multi pattern with moving block:
87 01 00 24 04 00 00 FF
TPG video standard:
87 01 00 24 01 0p 0q FF pq = 01 for 1080p50 pq = 09 for 1080p60 pq = 11 for 720p50
pq = 19 for 720p60
