[Outline]
This IC is a one-chip IC integrating an I
2C BUS controlled AV switch with 4 inputs and 3 outputs with a 6-channel video driver with a built-in LPF. 2 outputs among 3 outputs of the AV switch are 75Ωdrivers, whichis ideal for analog interface for recording equipment such as 2-SCART compatible DVD recorders for Europe.
[Features]
(1) |
Serially controlled with I2C BUS |
(2) |
Provided in a small package (SSOP-42) with an extensive function of a switch + driver |
(3) |
Optimized pin assignment considering the device architecture
(non-complicated board layout can berealized) |
(4) |
6-channel video driver including a high performance 4th-order LPF |
(5) |
Audio output that is programmable between 0dB and 6dB and includes a newly-developed adjustable gainamplifier |
(6) |
Includes auto power saving function when Vcc=12V is off (between Vcc=5V, 12V)
(when Vcc=12V is on, power saving is also possible by serial control) |
[Package]
[Applications]
(1) DVD recorders
(2) VCRs
(3) STBs
(4) Recording equipment
