Preliminary Information Features Preliminary Information TMC2069P7C PRODUCT SPECIFICATION Functional Description Setup Procedure The TMC2069P7C is designed to demonstrate the performance of the TMC3003 Digital to Analog converter. It also offers an example of design practices that result in highquality video performance. 1. To set up the output levels on the triple dac, place a digital NTSC unmodulated ramp that has peak white at the digital level 824 and blanking at 240. 2. The output analog levels should be 286 mV sync tip to blank level and 1.0V sync tip to peak white. If the output levels are incorrect, adjust the GREEN output using the potentiometer RV1. 3. Apply either the unmodulated digital ramp used in step 1 to the red and blue inputs to adjust the Pb/BLUE and Pr/RED outputs or apply SMPTE color bars and measure the Pb and Pr outputs. 4. Adjust RV2, to adjust the RED, and RV3, to adjust the BLUE output. The TMC3003 is a high-speed triple 10-bit D/A converter especially suited for video and graphics applications. It offers 10-bit resolution, TTL-compatible inputs, low power consumption, and requires only a single +5 Volt power supply. It has single ended current output, SYNC and BLANK control inputs, and a separate current source for adding sync pulses to the Green D/A converter output. It is ideal for generating analog RGB from digital RGB and driving computer display and video monitors. Three speed grades are available: 30, 50, and 80 Msps. The DAC module can be plugged into the TMC2068P7C decoder demonstration board to provide analog RGB or YPbPr outputs for viewing the decoder performance. The board can also be plugged into the 10-bit DICE line doubler demonstration board from Genesis. The input for the Genesis 10 bit line doubler board is being provided by the TMC2067P7C 10 bit ADC demonstration board connected to the TMC2068P7C decoder demonstration board. A set of switches routes the triple DAC outputs to either the VGA connector or the component video connectors. The SYNC and BLANK signals to the triple DAC are required for the VGA mode are disabled when the component video output is required. The component video connectors provide sync on green. a. If using the unmodulated ramp, match the output voltage levels to the values on the green channel. b. If using the SMPTE color bars, the level of Pb and Pr peak to peak should be 525 mV. 1.0V 286 mV Figure 2.

Output Low Pass Filters 2 6 MHz PRODUCT SPECIFICATION Power Supply Requirements The TMC2069P7C board requires 1.5 Amps from the +5 Volt power supply and 0.5 Amps from the -5 Volt power supply. The -5 Volt power supply powers the SMA filters. The +5 Volt power supply not only drives TTL logic devices but it also provides the power and voltage references to the TMC3003. Therefore, it is recommended that a bench power supply be used with the cable lengths kept to a minimum. TMC2069P7C The response at 5.0MHz typically varies<±0.25dB with supplies of ±5V to ±8V. When operating in the 0dB gain mode, pin 6 must be well isolated from ground planes. When operating in the +6dB gain mode, pin 6 must have a low resistance path to ground. For more information please contact Microelectronic Module Corporation (MMC) at 414-785-6506. Output Low-Pass Filters Preliminary Information The 601-003 filters are high end broadcast quality filters. They are Virtual 601 post filters with a bandwidth of 5.75MHz. 5-pole, sharp cutoff, Elliptic response, with 3 sections of group delay equalization. These filters were designed for SinX/X compensated CCIR 601 luminance applications and make an excellent post-filter following a D/A converter. 3 4 IPCONN IPCONN PXCK VSYNC HSYNC BLANK B[0:9] G[0:9] R[0:9] POWER POWER 3003 PXCK_ VSYNC_ HSYNC BLANK B[0:9] G[0:9] R[0..9] -HS -VS IOR IOG IOB Figure 3.

Damage may occur if they are connected together! • The RESET pin on the input edge connector should be connected directly to the RESET pin on the output connector. A link should be used to connect any pulse to the RESET line. • XPXCK is a two times pixel clock fed BACKWARD. • XHSYNC and XVSYNC are timing reference signals fed BACKWARD. • The MASTER/SLAVE, XDIR, PGM_IN and RESET pins on the input edge connector should be connected to +5V through a 10k pull up resistor. • The MASTER/SLAVE signal states if a board is a MASTER or a SLAVE board. This signal is fed FORWARD. A MASTER board produces the PXCK, HSYNC, and VSYNC signals, and a SLAVE board expects to receive XPXCK, XHSYNC, XVSYNC, etc . • The CLAMP signal is fed BACKWARD from a MASTER to a SLAVE board. The CLAMP signal should not be fed FORWARD. • XDIR is fed FORWARD and controls in which direction the XRS[3:0] data flows. • • • • • PGM_IN is a negative going pulse, logically ANDed with the onboard program start pulse, for initiating the programming sequence for components on that board. Care must be taken to ensure that multiple devices do not try to drive the RBUS at any given time. Minimum width of PGM_IN is 1uS. 11 Related Products TMC2068P7C Decoder demonstration board TMC2067P7C ADC demonstration board Raydemo software TMC2070P7C R-bus interface board TMC2069P7C PRODUCT SPECIFICATION Ordering Information Product Number Temperature Range Speed Grade Screening Package TMC2069P7C 25°C 80 MHz Commercial 4” by 5” Printed Circuit Board TMC2069P7C TMC2069P7CG1 25°C 80 MHz Commercial 4” by 5” Printed Circuit Board TMC2069P7CG Package Marking Notes: 1.
