249 / 259 page  Revision 1.1 249 www.national.com Electrical Specifications (Continued) 5.6 DISPLAY CHARACTERISTICS The following tables and figures describe the characteris- tics of the CRT, TFT/TV and MPEG Display interfaces. It is divided into the following categories: • CRT Display Recommended Operating Conditions • CRT Display Analog (DAC) Characteristics • Display Miscellaneous Characteristics • CRT, TFT/TV and MPEG Display Timing Additionally, Figure 5-13 on page 252 is provided showing a typical video connection diagram. Table 5-14. CRT Display Recommended Operating Conditions Symbol Parameter Min Typ Max Units Comments AVDD Power Supply connected to AVDD1,AVDD2 and AVDD3 3.14 3.3 3.46 V RL Output Load on each of the pins IOUTR, IOUTG and IOUTB 37.5 Ohms R1, R2, and R3 as shown in Figure 5-13 on page 252 IOUT Output Current on each of the pins IOUTR, IOUTG and IOUTB 21 mA RSET Value of the full-scale adjust resistor connected to IREF 680 Ohms This resistor should have a 1% tolerance. VEXTREF External voltage reference con- nected to the EXTVREFIN pin 1.235 V Table 5-15. CRT Display Analog (DAC) Characteristics Symbol Parameter Min Typ Max Units Comments (Note 1) VOM Output Voltage 0.735 V VOC Output Current 20 mA INL Integral Linearity Error +/-1 LSB DNL Differential Linearity Error +/-1 LSB tFS Full Scale Settling Time 2.5 ns -- DAC-to-DAC matching 5 % -- Power Supply Rejection 0.7 % @ 1 KHz tRISE Output Rise Time 3.8 ns Note 2 and Note 3 tFALL Output Fall Time 3.8 ns Note 2 and Note 4 1. All tests, unless otherwise specified, are at VDD = 3.14V to 3.46V, TC = 0°C to 85°C, and CL =50 pF. 2. Timing measurements are made with a 75 ohm doubly-terminated load, with VEXTREF = 1.235V and RSET = 680 ohms. 3. 10% to 90% of full-scale transition. 4. Full-scale transition: time from output minimum to maximum, not including clock and data feedthrough. |
