LT1203/LT1205

150MHz Video Multiplexers

DESCRIPTIO

EATURE

■

The LT1203 is a wideband 2-input video multiplexer

designed for pixel switching and broadcast quality rout-

ing. The LT1205 is a dual version that is configured as a

4-input, 2-output multiplexer.

–3dB Bandwidth: 150MHz

0.1dB Gain Flatness: 30MHz

Channel-to-Channel Switching Time: 25ns

Turn-On/Turn-Off Time: 25ns

High Slew Rate: 300V/µs

These multiplexers act as SPDT video switches with 10ns

transition times at toggle rates up to 30MHz. The –3dB

bandwidth is 150MHz and 0.1dB gain flatness is 30MHz.

Many parts can be tied together at their outputs by using

the enable feature which reduces the power dissipation

and raises the output impedance to 10MΩ. Output capaci-

than 3dB into a 50pF load. Channel crosstalk and disable

isolation are greater than 90dB up to 10MHz. An on-chip

buffer interfaces to fast TTL or CMOS logic. Switching

transients are only 50mV with a 25ns duration. The

LT1203 and LT1205 outputs are protected against shorts

to ground.

Disabled Output Impedance: 10MΩ

Differential Phase: 0.02°

Wide Supply Range: ±5V to ±15V

The LT1203/LT1205 are manufactured using Linear

Technology’sproprietarycomplementarybipolarprocess.

The LT1203 is available in both the 8-lead PDIP and SO

package while the LT1205 is available in the 16-lead

narrow body SO package.
