2. IC1301 (VHINJM2750M-1Y)
The NJM2750 is a 4-input/1-output stereo audio selector. It contains a switch operational amplifier and shows lower noise, lower distortion and higher
channel separation than an ordinary multiplexer or analog switch.
Description:
•
Operating voltage (4.7 - 13V)
•
4-input/1-output audio selector
•
Stereo 2-channel
•
Low output noise (-110dBV typ.)
•
Low distortion (0.005% typ.)
3. IC1401 (VHISM5309AV-1Y)
The SM5309A is a 3ch video buffer with a built-in 5th-order low pass filter. The cutoff frequency of the low pass filter can be adjusted between 4MHz
and 40MHz in 256 steps. The low pass filter supports analog inputs/outputs of video signal device of 480i to 1080i format. When it is used as an input
system, it functions as an antialiasing filter of the rear-stage ADC system. If used as an output system, aliasing noise from the video DAC or exoge-
nous noise is eliminated, and the terminating resistance of up to 300
Ω
can be driven. The cutoff frequency or signal input method can be controlled by
I2C-BUS.
Description:
•
Supply voltage: Analog: 4.75 - 5.25V
Digital: 3.0 - 5.5V
•
Low pass filter function where cutoff frequency can be adjusted in 256 steps
Cutoff frequency range: 4MHz - 40MHz (RISET = 1.8k
Ω
)
•
Filter bypath mode function supporting the resolution of SXGA
•
Switchable to the half fc mode suitable for the component signal (CH-2, CH-3)
•
2-input multiplexer function (switchable by the I2C-BUS or MUXSEL terminal)
•
For the video input terminal, the sync-tip clamp/bias/direct input can be selected per channel.
•
Possible to drive the terminating resistance of up to 300
Ω
•
Output gain: 0dB
•
Power down function
– Consumption current at power down: 1mA or less
•
Control by I2C-BUS interface
– Transfer rate: First mode (400kbit/s) supported
