product specification ml6429 rev. 1.0.0 8/28/03 5 functional description the ml6429 is a quad monolithic continuous time analog video ?ter designed for reconstructing signals from four video d/a sources. the ml6429 is intended for use in ac coupled input and output applications. the ?ters approximate a 4th-order butterworth characteris- tic with an optimization toward low overshoot and ?t group delay. all outputs are capable of driving 2v p-p into ac cou- pled 150 ? video loads, with up to 35pf of load capacitance at the output pin. likewise, they are capable of driving a 75 ? load at 1v p-p . all channels are clamped during sync to establish the appro- priate output voltage swing range. thus the input coupling capacitors do not behave according to the conventional rc time constant. clamping for all channels settles within 10ms of a change in video sources. input coupling capacitors of 0.1? are recommended for all channels. during sync, a feedback error ampli?r sources/ sinks current to restore the dc level. the net result is that the av erage input current is zero. any change in the input cou- pling capacitors value will linearly affect the clamp response times. the rgb channels have no pulldown current sources and are essentially tilt-free. the cv channel's inputs sink less than 1? during active video, resulting in a tilt of less than 1mv for a 220 ?. up to 1000? recommended to reude tilt for tv applications. swap multiplexer control output pins cv out 1/y out a and cv out 2/y out b are each independently selectable between three input sources (cv inf , and cv inu a, cv inu b) depending on the digital inputs swap cvf, swap cvu, and a/b mux. this allows the two outputs to remain independent and pass straight through, to remain independent but swapped, or for both outputs to have the same signal sourcing from either cv inf or cv inf a, cv inu b (see table 1). if swap cvf is forced to logic low, then cv out 2/y out b sources from cv inu a/ y2, cv inu b/y3. if swap cvu is logic low, cv out 1/ y out a outputs video from the cv inu a, cv inu b input. if swap cvf is logic high, cv out 2/y out b outputs from cv inf /y1 input. if swap cvu is high, cv out 1/y out a outputs from cv inu a/y2 or cv inu b/y3. both swap cvf and swap cvu will pull low if they are not driven. the ml6429 is robust and stable under all stated load and input conditions. bypassing both v cc pins directly to ground ensures this performance. two ml6429s can be connected in a master-slave sync con?uration. when using this con?uration, only the ?aster?ml6429 is required to have a signal with embedded sync present on the cv inu a, cv inu b input. in the absence of sync on the cv inu a or cv inu b input of the ?lave?ml6429, the ?lave?ic will have its sync in input connected to the sync out output of the ?aster?ml6429. syncin and syncout pins each ml6429 has two sync detectors which control the dc restore functions. the ?tered channel has its own detector, which controls the dc restore function during the horizontal sync period of the cv inf /y1 input. the other sync detector controls the dc restore functions for the ?tered channels based upon the composite or luma input at the cv inu a/y2 or cv inu b/y3 pins. required setup: a composite or luma or green signal must be present on cv inu a/y2 or cv inu b/y3 inputs to provide necessary sync signals to other channels (r,g,b,y,c). other- wise, sync must be provided at the syncin pin. for rgb applications, the green channel with sync can be used as an input to cv inu a/y2 or cv inu b/y3. the syncout pin outputs a logic high when it detects the horizontal sync of either the cv inu a/y2 or cv inu b/y3 input (note that one input is selected by the a/b mux pin). the syncin pin is an input for an external h-sync logic signal to enable or disable the internal dc restore loop for the ?tered channels. when syncin is logic high, the dc restore function is enabled. f or normal operation, the syncout pin is connected to the syncin pin (see figure 4). if the cv inu does not have an embedded sync, an external sync can be applied on the syncin pin. in master-slave con?urations, the syncout of a ml6429 master can be used as the syncin of a ml6429 slave. video i/o description each input is driven by either a low impedance source or the output of a 75 ? terminated line. the input is required to be ac coupled via a 0.1? coupling capacitor which gives a nominal clamping time of 10ms. all outputs are capable of driving an ac coupled 150 ? load at 2v p-p or 1v p-p into a 75 ? load. at the output pin, up to 35pf of load capacitance can be driven without stability or slew issues. a 220? ac coupling capacitor is recommended at the output to reduce power consumption. analog multiplexer control the four ?ter channels each have two input multiplexers which are paired to select between two four-channel video sources (i.e., composite video plus rgb component video). if a/b mux is forced to logic high, it will select bank of video inputs (cv inu a/y2, r in a/y4, g in a/y6, b in a/ c1) to be enabled. if a/b mux is logic low, then bank of video inputs (cv inu b/y3, r in b/y5,g in b/y7, b in b/ c2) will be selected. if the a/b mux is open, it will pull to logic high.

product specification ml6429 rev. 1.0.0 8/28/03 7 t ypical applications basic applications the ml6429 provides channels for two banks of inputs for rgb and composite video. the r and g channels can be used as luma inputs while the b channel can be used as a chroma input. composite outputs and an h-sync output is also provided. there are several con?urations available with the ml6429. figure 4 includes a list of basic output options for composite, s-video, tv modulator, and rgb outputs. note that each composite channel can drive a cv load or a channel modulator simultaneously. the ml6429 standalone can be used as an evc or scart cable driver with nine video sources (75 ? or low impedance buffer) and seven video outputs. all inputs and outputs are ac coupled. when driving seven loads, power dissipation must be measured to ensure that the junction temperature doesnt e xceed 120?. evc cable driving the ml6429 can be con?ured to drive composite video, s-video, and horizontal sync through an evc connector (figure 5). composite video and s-video inputs are ?tered through 4th-order butterworth ?ters and driven through internal 75 ? cable drivers. a buffered h-sync output is also av ailable. scart cable driving the ml6429 can be con?ured either as a scart cable driver (figure 4) or as a scart cable driver and s-video driver (figure 6). a horizontal sync output is also available. note that the ml6429 can be used in a master-slave mode where the sync-out from the master is used as the sync-in of the slave; this allows the cv, s-video, and rgb channels to operate under the same sync signals. note that in scart applications, it is not always necessary to ac couple the outputs. systems using scart connectors for rgb and composite video can typically handle between 0 and 2v dc offset (see dc coupled applications section). rgb applications rgb video can be ?tered and driven through the ml6429. f or sync suppressed rgb, the sync signal can be derived from syncin pin. osd (on-screen display) applications un?tered rgb video from an osd processor needs to be ?tered and then synchronized to a fast blanking interval or alpha-key signal for later video processing. with the total ?- ter delay being 80ns ?0ns, a d ?p-?p or similar delay ele- ment can be used to delay the fast blanking interval or alpha- ke y signal, which synchronizes the rgb and osd signals (figure 9). channel multiplexing the ml6429 can be con?ured for multiple composite chan- nel multiplexing (figure 8). composite and rgb sources such as vcrs, and digital mpeg 2 sources can be selected using the ml6429 swap mux controls. a/b mux, swap cvu, and swap cvf signals can be used to select and route from various input sources. dc coupled applications the 220? capacitor coupled with the 150 ? termination forms a highpass ?ter which blocks the dc while passing the video frequencies and avoiding tilt. lower values such as 10? would create a problem. by ac coupling, the average dc level is zero. thus, the output voltages of all channels will be centered around zero. alternately, dc coupling the output of the ml6429 is allowable. there are several tradeoffs: the average dc level on the outputs will be 2v; each output will dissipate an additional 40mw nominally; the application will need to accommodate a 1v dc offset sync tip; and it is recom- mended to limit one 75 ? load per output. however, if two loads are required to be driven at a time on the composite output while dc coupling is used, then the swap?ux and 5th line driver can be con?ured to enable the ?tered composite signal on both the 4th and 5th line drivers. thus, the composite load driving requirement is divided into two line drivers versus one. required setup: a composite or luma or green signal must be present on cv inu a/y2 or cv inu b/y3 inputs to provide necessary sync signals to other channels (r,g,b,y,c). other- wise, sync must be provided at the syncin pin. for rgb applications, the green channel with sync can be used as an input to cv inu a/y2 or cv inu b/y3. using the ml6429 for pal applications the ml6429 can be optimized for pal video by adding frequency peaking to the composite and s-video outputs. figure 10 illustrates the use of an additional external capaci- tor (300pf), added in parallel to the output source termina- tion resistor. this raises the frequency response from 1.0db down at 4.8mhz (for no peaking cap) to 0.2db down at 4.8mhz (for 300 pf), which allows for accurate reproduc- tion of the upper sideband of the pal subcarrier. figure 11 shows the frequency response of pal video with various val- ues of peaking capacitors (0pf, 220pf, 270pf, 300pf) between 0 and 10mhz. f or ntsc applications without the peaking capacitor, the rejection at 27mhz is 40db (typical). for pal applications with the peaking capacitor, the rejection at 27mhz is 34db (typical). (figure 12). the differential group delay is shown in figure 13 with and without a peaking capacitor (0pf, 220pf, 270pf, and 300pf) varies slightly with capacitance; from 8ns to 13ns.
