max4090 3v/5v, 6db video buffer with sync-tip clamp and 150na shutdown current _______________________________________________________________________________________ 7 detailed description the max4090 3v/5v, 6db video buffer with sync-tip clamp and low-power shutdown mode is available in tiny sot23 and sc70 packages. the max4090 is designed to drive dc-coupled, 150 back-terminated video loads in portable video applications such as digital still cams, portable dvd players, digital camcorders, pdas, video- enabled cell phones, portable game systems, and note- book computers. the input clamp positions the video waveform at the output and allows the max4090 to be used as a dc-coupled output driver. the max4090 operates from a single 2.7v to 5.5v sup- ply and consumes only 6.5ma of supply current. the low-power shutdown mode reduces the supply current to 150na, making the max4090 ideal for low-voltage, battery-powered video applications. the input signal to the max4090 is ac-coupled through a capacitor into an active sync-tip clamp cir- cuit, which places the minimum of the video signal at approximately 0.38v. the output buffer amplifies the video signal while still maintaining the 0.38v clamp volt- age at the output. for example, if v in = 0.38v, then v out = 0.38v. if v in = 1.38v, then v out = 0.38v + (2 x 1v) = 2.38v. the net result is that a 2v video output signal swings within the usable output voltage range of the output buffer when v cc = 3v. shutdown mode the max4090 features a low-power shutdown mode (i shdn = 150na) for battery-powered/portable applica- tions. pulling the shdn pin high enables the output. connecting the shdn pin to ground (gnd) disables the output and places the max4090 into a low-power shutdown mode. applications information input coupling the max4090 the max4090 input must be ac-coupled because the input capacitor stores the clamp voltage. the max4090 requires a typical value of 0.1? for the input clamp to meet the line droop specification. a minimum of a ceramic capacitor with an x7r temperature coefficient is recommended to avoid temperature-related prob- lems with line droop. for extended temperature opera- tion, such as outdoor applications, or where the impressed voltage is close to the rated voltage of the capacitor, a film dielectric is recommended. increasing the capacitor value slows the clamp capture time. values above 0.5? should be avoided since they do not improve the clamp? performance. the active sync-tip clamp also requires that the input impedance seen by the input capacitor be less than 100 typically to function properly. this is easily met by the 75 input resistor prior to the input-coupling capacitor and the back termination from a prior stage. insufficient input resistance to ground causes the max4090 to appear to oscillate. never operate the max4090 in this mode. using the max4090 with the reconstruction filter in most video applications, the video signal generated from the dac requires a reconstruction filter to smooth out the signal and attenuate the sampling aliases. the max4090 is a direct dc-coupled output driver, which can be used after the reconstruction filter to drive the video signal. the driving load from the video dac can be varied from 75 to 300 . a low input impedance (<100 ) is required by the max4090 in normal opera- tion, special care must be taken when a reconstruction filter is used in front of the max4090. for standard video signal, the video passband is about 6mhz and the system oversampling frequency is at 27mhz. normally, a 9mhz bw lowpass filter can be used for the reconstruction filter. this section demon- strates the methods to build simple 2nd- and 3rd-order passive butterworth lowpass filters at the 9mhz cutoff frequency and the techniques to use them with the max4090 (figures 1 and 4). 2nd-order butterworth lowpass filter realization table 1 shows the normalized 2nd-order butterworth lpf component values at 1rad/s with a source/load impedance of 1 . with the following equations, the l and c can be calcu- lated for the cutoff frequency at 9mhz. table 2 shows the appropriated l and c values for different source/ load impedance, the bench measurement values for the -3db bw and attenuation at 27mhz. there is approximately 20db attenuation at 27mhz, which effec- tively attenuates the sampling aliases. the max4090 requires low input impedance for stable operation and it does not like the reactive input impedance. for r1/r2 greater than 100 , a series resistor r is (figure 1) r n 1 = r n 2 ( )c n 1 (f) l n 1 (h) 1 1.414 1.414 table 1. 2nd-order butterworth lowpass filter normalized values
max4090 between 20 to 100 is needed to isolate the input capacitor (c4) to the filter to prevent the oscillation problem. figure 2 shows the frequency response for r1 = r2 = 150 . at 6mhz, the attenuation is about 1.4db. the attenuation at 27mhz is about 20db. figure 3 shows the multiburst response for r1 = r2 = 150 . 3rd-order butterworth lowpass filter realization if more flat passband and more stopband attenuation are needed, a 3rd-order lpf can be used. the design procedures are similar to the 2nd-order butterworth lpf. table 3 shows the normalized 3rd-order butterworth lowpass filter with the cutoff frequency at 1 rad/s and the stopband frequency at 3 rad/s. table 4 shows the appropriated l and c values for different source/load impedance and the bench measurement values for -3db bw and attenuation at 27mhz. the attenuation is over 40db at 27mhz. at 6mhz, the attenuation is approximately 0.6db for r1 = r2 = 150 (figure 5). c c fr l lr f n cl nl c == 22 3v/5v, 6db video buffer with sync-tip clamp and 150na shutdown current 8 _______________________________________________________________________________________ 0.1 1 10 100 frequency response frequency (mhz) gain (db) 0 -60 -50 -40 -30 -20 -10 r2 150 r1 150 c1 150pf l1 3.9 h c4 0.1 f r3 75 c7 1 f in out gnd fb shdn v cc v cc v cc v out video current dac r is 49.9 2-pole reconstruction lpf max4090 figure 1. 2nd-order butterworth lpf with max4090 figure 2. frequency response v out 500mv/div 10 s/div v in 500mv/div figure 3. multiburst response
