Line-up of products with built-in video amplifier and video driver
3-input, 1-output video switch
BH76330FVM, BH76331FVM, BH76332FVM, BH76333FVM
●
General
BH76330FVM, BH76331FVM, BH76332FVM, and BH76333FVM are video signal switching ICs, each with three inputs and
one circuit input, which feature wide dynamic range and frequency response. Since these ICs can be used with low voltage
starting at VCC = 2.8 V, they are applicable not only in stationary devices but also in mobile devices.
This product line-up supports a broad range of input signals, depending on whether or not a 6-dB video amplifier and video
driver are included and what combination of sync tip clamp type and bias (resistor termination) type inputs are used.
●
Features
1) Able to use a wide range of power supply voltage, from 2.8 V to 5.5 V
2) Wide output dynamic range
3) Excellent frequency response
(BH76330FVM and BH76331FVM: 100 kHz/10 MHz 0 dB [Typ.], BH76332FVM and BH76333FVM:
MHz 0 dB [Typ.])
4) No crosstalk between channels (Typ. -65 dB, f = 4.43 MHz)
5) Built-in standby function, circuit current during standby is 0 µA (Typ.)
6) Sync tip clamp input (BH76330FVM, BH76332FVM)
7) Bias input (Zin = 150 k) (BH76331FVM, BH76333FVM)
8) 6-dB amp and 75 driver are built in (BH76330FVM, BH76331FVM)
9) Enables two load drivers [when using output coupling capacitor] (BH76330FVM, BH76331FVM)
10) Able to be used without output coupling capacitor (BH76330FVM)
11) MSOP8 compact package
●
Applications
Input switching in car navigation systems, TVs, DVD systems, etc.
