LT1203/LT1205 150MHz Video Multiplexers DESCRIPTIO FEATURES n 3dB Bandwidth: 150MHz The LT1203 is a wideband 2-input video multiplexer n 0.1dB Gain Flatness: 30MHz designed for pixel switching and broadcast quality rout- n Channel-to-Channel Switching Time: 25ns ing. The LT1205 is a dual version that is configured as a n Turn-On/Turn-Off Time: 25ns 4-input, 2-output multiplexer. n High Slew Rate: 300V/s These multiplexers act as SPDT video switches with 10ns n Disabled Output Impedance: 10M transition times at toggle rates up to 30MHz. The 3dB n 50mV Switching Transient bandwidth is 150MHz and 0.1dB gain flatness is 30MHz. n Channel Separation at 10MHz: >90dB Many parts can be tied together at their outputs by using n Differential Gain: 0.02% the enable feature which reduces the power dissipation n Differential Phase: 0.02 and raises the output impedance to 10M. Output capaci- n Wide Supply Range: 5V to 15V tance when disabled is only 3pF and the LT1203 peaks less n Output Short-Circuit Protected than 3dB into a 50pF load. Channel crosstalk and disable n Push-Pull Output isolation are greater than 90dB up to 10MHz. An on-chip buffer interfaces to fast TTL or CMOS logic. Switching APPLICATI S transients are only 50mV with a 25ns duration. The LT1203 and LT1205 outputs are protected against shorts n Broadcast Quality Video Multiplexing to ground. n Picture-in-Picture Switching n The LT1203/LT1205 are manufactured using Linear HDTV n Technologys proprietary complementary bipolar process. Computer Graphics n The LT1203 is available in both the 8-lead PDIP and SO Title Generation n package while the LT1205 is available in the 16-lead Video Crosspoint Matrices n narrow body SO package.
