Circuit Description; Vc-31 Board; Ld-119 Board; Cd-83 Board - Sony FCB-ER8300 Servicehandbuch

2-1. VC-31 Board

. The VC-31 board consists of a core IC that performs video output, camera control, lens control, VISCA
communication, and USB communication, a DD converter that generates system power, a reset signal
generator circuit, an inter-board connection connector, and an external equipment connection connector.
. The VC-31 board is connected with LD-119 and SE-1147 boards using a flexible flat cable and con-
nected with a CD-83 board using a flexible wiring panel. It is also connected with external equipment
using a 30-pin fine-wire coaxial cable.
. The VC-31 board inputs the CMOS video signal from the CD-83 board and outputs it to the external
equipment connector according to an HDMI format after signal processing.
. DC power is supplied from the external equipment so as to generate 1.0 VDC, 1.2 VDC, 1.8 VDC, 3.1
VDC, and 5.0 VDC required for a system.
. The VC-31 board performs VISCA communication for the camera control from the external equipment
and performs USB communication for upgrading of user firmware.

2-2. LD-119 Board

. The LD-119 board consists of a drive IC, which moves a lens, and an inter-board connection connector.
. The LD-119 board is connected with a VC-31 board using a 50-pin flexible flat cable and connected
with a lens using a flexible wiring panel.
. The LD-119 board drives the focus, zoom, iris, and IR of a lens.

2-3. CD-83 Board

. The CD-83 board consists of a CMOS sensor and inter-board connection connector.
. The CD-83 board is connected with a VC-31 board using a 51-pin flexible wiring panel.
. The CD-83 board outputs the Sub-LVDS video signal of a CMOS sensor to the VC-31 board.

2-4. SE-1147 Board

. The SE-1147 board consists of a GYRO sensor, GYRO signal amplifier, and inter-board connection
connector.
. The SE-1147 board is connected with a VC-31 board using a 6-pin flexible flat cable.
. The SE-1147 board outputs the PITCH/YAW analog signal of a GYRO sensor to the VC-31 board.
