MITSUBISHI ICs (AV COMMON) M65530FP TRIPLE 10-BIT VIDEO D-A CONVERTER CURRENT SETTING RESISTOR (Rref) AND OUTPUT LOAD RESISTOR (R L) (external components) Full-scale output amplitude (VFS ) of each D/A converter is ; VFS = (VG / Rref) x 16 x RL (VP-P). where VG = 1.28 V, Rref = 768 Ω , RL = 75 Ω and VDD = 5.0V. The full-scale output of about 2.0 VP-P is available by setting RL and Rref to 75 Ω and 768 Ω , respectively. An output impedance of the analog output terminal is almost the same as the load resistor (RL). NOTES TO THE OPERATION 1. Both a ground and a supply planes in a PCB should be as wide as possible for reducing a parasitic inductance and resistance. Especially, for the better performance, the analog plane needs to be much wider. 2. A tantalum or electrolytic capacitor of 10µF or more and a ceramic capacitor of 0.01µF are tied together, which are connected between a digital supply and ground, also between a analog supply and ground. These capacitors should be placed as close as possible to the IC. They work as bypass capacitors for preventing a degradation in the performance by a supply voltage fluctuation caused by digital signals including a clock and digital inputs and so on. 3. The analog output should be isolated as much as possible from a clock and digital inputs, thus minimizing decoupling and interactive noise.
