Tx-167B Board; Board - Sony HDCU3500 Service Manual

this FPGA also has the HD-to-4K up-conversion function. Furthermore, this FPGA can convert video data from camera
to 3G SDI (Level-A/B) or HD SDI data, and when the HZCU-UHD35 option is installed, 4K video data can be output
with 12G SDI or 3G SDI (2SI, SQD) in addition to the above. The TX-167A board contains output connectors UHD
SDI A and UHD SD B (J301, J302) and input/output connectors UHD SDI C and UHD SDI D (J303, J304), enabling
output of up to 4-channel SDI video signals.
UHD return video signals
This function is available only when the HZCU-UHD35 option is provided. UHD return video signals are input from
the UHD SDI C and UHD SDI D connectors (J303, J304) on the TX-167A board. Only the 12G SDI signal can be input.
This input signal is sent to the VIF-75 board. The frame synchronization function of the FPGA (IC1501) also supports
asynchronous return signals. UHD return video signals are sent to the camera through the VIF-75 board.

TX-167B Board

The TX-167B board is mounted in HDCU5500 and HKCU-FB50.
Data transmission between the TX-167B board and the camera
Data is transmitted from the Fiber connector through CN201.
Main-line video signals
The video data that is transmitted from the camera is send to the VIF-75 board.
The TX-167B board processes four SDI output signals and video data to be sent to the VIF-75 board and the NET-37
board. Four DDR3 SDRAM ICs (IC1201, IC1202, IC1301, and IC1302) are connected to the TX-167B board. This
board is equipped with the 4K/HD HFR video processing function.
Four DDR4 SDRAM ICs (IC2101, IC2102, IC2201, and IC2202) are also connected to the FPGA (IC1501). This FPGA
is equipped with the 4K/HD HFR video processing function, 720P conversion function, and P-to-i (Progressive to
interlace) conversion function in addition to the timing adjustment function.
Furthermore, this FPGA can convert 4K video data from camera to 12G SDI, 6G SDI, 3G SDI (Level-A/B, 2SI, SQD),
or HD SDI (2SI, SQD) data.
The TX-167B board contains output connectors UHD SDI A and UHD SD B (J301, J302) and input/output connectors
UHD SDI C and UHD SDI D (J303, J304), enabling output of up to 4-channel SDI video signals.
UHD return video signals
UHD return video signals are input from the UHD SDI C and UHD SDI D connectors (J303, J304) on the TX-167B
board. The 12G SDI and 6G SDI signals can be input. The input signal is sent to the camera through the VIF-75 board.
UHD TRUNK signal
The UHD SDI B connector (J301) on the TX-167B board can be used as a UHD TRUNK output connector.
UHD PROMPTER signal
The UHD SDI D connector (J303) on the TX-167B board can be used as a UHD PROMPTER input connector.
The UHD PROMPTER signal is sent to the camera through the FPGA (IC601) on the TX-167B board.

Audio signals
The PGM signal that is input to the D-sub connector is transferred to the A/D and D/A converter ICs (IC2614, IC2615)
through the B to B connector (CN303) in which the signal is converted to a digital signal, and then the digital signal is
input to the FPGA (IC1200). The System Intercom signal that is input to the D-sub connector is transferred to the A/D
and D/A converter IC (IC2900) through the B to B connector (CN303) in which the signal is converted to a digital signal,
and then the digital signal is input to the FPGA (IC1200).
The TALK signal of the front INTERCOM that is input from the FP-305 board to the CN400 connector is converted to
a digital signal in the A/D and D/A converter IC (IC2513), and then the digital signal is input to the FPGA (IC1200).
