PROJECTOR IMAGE AND CONTROL PORT SIGNALS
The DLPC200 provides two input ports for graphics and motion video inputs. The signals listed below support the
two input interface modes.
Below are the two input image interface modes, signal descriptions, and pins needed on the DLPC200.
PORT 1, 28 pins (HDMI connector)
PORT1_D(23-0) – Projector Data
PORT1_VSYNC – Vertical Sync
PORT1_HSYNC – Horizontal Sync
PORT1_IVALID – Data Enable
PORT1_CLK – Projector Clock (rising edge, or falling edge, to capture input data)
PORT 2, 28 pins (Expansion connector)
PORT2_D(23-0) – Projector Data
PORT2_VSYNC – Vertical Sync
PORT2_HSYNC – Horizontal Sync
PORT2_IVALID – Data Enable
PORT2_CLK – Projector Clock (rising edge, or falling edge, to capture input data)
Two control interfaces, USB and SPI, are provided to configure the DLPC200, as well as to transmit pattern data
to memory for structured light mode. Below are the pins needed for the SPI and USB control interfaces.
USB, 48 MHz
USB_CLK - USB clock
USB_CTRL1 - FIFO full flag
USB_CTRL2 - FIFO empty flag
USB_FD(15-0) - USB data
USB_PA02 - FIFO output enable for reads
USB_PA04 - FIFO address bit
USB_PA05 - FIFO address bit
USB_RDY1 - Write enable
USB_RDY0 - Read enable
SPI, 5 MHz
SLAVE_SPI_CLK - SPI clock
SLAVE_SPI_ACK - busy signal that holds off additional transactions until the slave has completed
processing data
SLAVE_SPI_MISO - output from slave
SLAVE_SPI_MOSI - output from master
SLAVE_SPI_CS - Slave select
Images are displayed via control of the DMD and DAD. The DLPC200 DMD interface consists of a 200 MHz
(nominal) half bus DDR output-only interface with LVDS signaling. The serial communications port (SCP), 125
kHz nominal, is used to read or write control data to both the DMD and the DAD. The signals listed below
support data transfer to the DMD and DAD.
DMD, 200 MHz
DMD_CLK_AP, DMD_CLK_AN - DMD clock for A
DMD_CLK_BP, DMD_CLK_BN - DMD clock for B
DMD_DAT_AP, DMD_DAT_AN(1,3,5,7,9,11,13,15) - Data bus A (odd numbered pins are used for half
bus)
DMD_DAT_BP, DMD_DAT_BN(1,3,5,7,9,11,13,15) - Data bus B (odd numbered pins are used for half
bus)
DMD_SCRTL_AP, DMD_SCRTL_AN - S-control for A
DMD_SCRTL_BP, DMD_SCRTL_BN - S-control for B
