GENERAL DESCRIPTION The ADV7123-EP is a triple, high speed digital-to-analog converter (DAC) on a single monolithic chip. It consists of three high speed, 10-bit video DACs with complementary outputs, a standard TTL input interface, and a high impedance, analog output current source. The ADV7123-EP has three separate 10-bit-wide input ports. A single 3.3 V power supply and clock are the only components required to make the part functional. The ADV7123-EP has additional video control signals: composite SYNC and BLANK. The ADV7123-EP also has a power save mode. The ADV7123-EP is fabricated in a 5 V CMOS process. Its monolithic CMOS construction ensures greater functionality with lower power dissipation. The ADV7123-EP is available in a 48-lead LFCSP package. Full details about this enhanced product are available in the ADV7123 data sheet, which should be consulted in conjunction with this data sheet. PRODUCT HIGHLIGHTS 1. 2.

The ADV7123-EP exhibits high performance when operating with an internal voltage reference, VREF. DAC-to-DAC crosstalk is measured by holding one DAC high while the other two DACs are making low-to-high and high-to-low transitions. 4 Clock and data feedthrough is a function of the amount of overshoot and undershoot on the digital inputs. Glitch impulse includes clock and data feedthrough. 5 TTL input values are 0 V to 3 V, with input rise/fall times of 3 ns, measured at the 10% and 90% points. Timing reference points are 50% for inputs and outputs. 2 3 TIMING SPECIFICATIONS VAA = 3.0 V to 3.6 V, VREF = 1.235 V, RSET = 560 Ω, CL = 10 pF.

Pixel data is latched on the rising edge of CLOCK. R0, G0, and B0 are the least significant data bits. Unused pixel data inputs should be connected to either the regular printed circuit board (PCB) power or ground plane. Composite Blank Control Input (TTL Compatible). A Logic 0 on this control input drives the analog outputs— IOR, IOB, and IOG—to the blanking level. The BLANK signal is latched on the rising edge of CLOCK. When BLANK is a Logic 0, the R0 to R9, G0 to G9, and B0 to B9 pixel inputs are ignored. Composite Sync Control Input (TTL Compatible). A Logic 0 on the SYNC input switches off a 40 IRE current source. The sync current is internally connected to the IOG analog output. SYNC does not override any other control or data input; therefore, it should only be asserted during the blanking interval. SYNC is latched on the rising edge of CLOCK. If sync information is not required on the green channel, the SYNC input should be tied to Logic 0. Analog Power Supply (3.3 V ± 10%). All VAA pins on the ADV7123-EP must be connected. Clock Input (TTL Compatible). The rising edge of CLOCK latches the R0 to R9, G0 to G9, B0 to B9, SYNC, and BLANK pixel and control inputs. Typically, the CLOCK input is the pixel clock rate of the video system. CLOCK should be driven by a dedicated TTL buffer. Ground. The GND pins must be connected. Differential Red, Green, and Blue Current Outputs (High Impedance Current Sources). These RGB video outputs are specified to directly drive RS-343A and RS-170 video levels into a doubly terminated 75 Ω coaxial cable. If the complementary outputs are not required, these outputs should be tied to ground. Red, Green, and Blue Current Outputs (High Impedance Current Sources). These RGB video outputs are specified to directly drive RS-343A and RS-170 video levels into a doubly terminated 75 Ω coaxial cable. All three current outputs should have similar output loads whether or not they are all being used. Compensation Pin for the Internal Reference Amplifier. A 0.1 μF ceramic capacitor must be connected between COMP and VAA. Voltage Reference Input for DACs or Voltage Reference Output (1.235 V). The VREF pin is normally terminated to VAA through a 0.1 μF capacitor. However, the ADV7123-EP can be overdriven by an external 1.23 V reference (AD1580), if required. Rev. 0 | Page 8 of 12 ADV7123-EP Pin No. 37 Mnemonic RSET 38 EP PSAVE Exposed Pad Description A resistor (RSET) connected between this pin and GND controls the magnitude of the full-scale video signal. Note that the IRE relationships are maintained, regardless of the full-scale output current. For nominal video levels into a doubly terminated 75 Ω load, RSET = 530 Ω. The relationship between RSET and the full-scale output current on IOG (assuming ISYNC is connected to IOG) is given by RSET (Ω) = 11,445 × VREF (V)/IOG (mA) The relationship between RSET and the full-scale output current on IOR, IOG, and IOB is given by IOG (mA) = 11,445 × VREF (V)/RSET (Ω) (SYNC being asserted) IOR, IOB (mA) = 7989.6 × VREF (V)/RSET (Ω) The equation for IOG is the same as that for IOR and IOB when SYNC is not being used, that is, SYNC is tied permanently low. Power Save Control Pin. Reduced power consumption is available on the ADV7123-EP when this pin is active. The exposed paddle on the underside of the package must be soldered to the ground plane to increase the reliability of the solder joints and to maximize the thermal capability of the package.
