HI,
I am currently trying to propose an imaging analog front-end device for use in the facsimile equipment to the customer.
Imaging sensor to use in the facsimile equipment of the customer is DL100-05EUJS-3.
DL100-05EUJS-3 : 200 DPI A4 size contact image sensor spec
1. Product Description
Number Of Sensor Elements : 1728(1 to 1712 dots available)
Resolution : 200 DPI
Scanning speed : 5 msec/line
Light Source : Wavelength 570 nm
Data Output : 1 Analogue
2. Electrical Characteristics
Power Supply (VDD) 3.0V(min) 3.3V(typ) 3.6V(max)
Input CLK Voltage (VIH) SI & CLK 2.1V(min)
Input CLK Voltage (VIL) SI & CLK 1.08V(max)
Input CLK Current (IIH) SI & CLK 500uA(max)
Input CLK Current (IIL) SI & CLK -0.2mA(max)
CLK Frequency (Fmax) 0.5MHz(typ) 0.77MHz(max)
Clock Duty (tw/to) 75%(typ)
For reference, we will describe a similar product data sheet of the linked VDD = 5V specification.

The demand for imaging analog front-end device from customers.
· Timing Generator is built
· CMOS output
I have some questions about AFE.
Q1: The VSP5610 data sheet of the model number that I heard from the customer, there is no description of the CIS (contact image sensor).
Can we use this CIS in the VSP5610 device?
Q2: RLCK of the VSP5610 is 1MHz(min). (datasheet 3-page)
Clock frequency of this CIS is 0.77MHz(max).
Do you have a track record that corresponds with an external frequency divider circuit in order to lower this CIS clock frequency in the VSP5610?
Q3: Do the MODE3 of LM98714 or LM98722 be used to the CIS(Mono color)?
Q4: Do you have a track record that corresponds with an external frequency divider circuit in order to lower this CIS clock frequency in the MODE1 of LM98714 or LM98722?
Q5：Are there any other imaging analog front-end devices that the CIS can use?
Please send me the informations.
Best Regards
