Hi,
Anyone who can provide me datasheet of a Docking Station Connector, Male, Vertical Mounted, either through-hole or surface mounted with 30 pins (0.5mm pitch).
I already found one that was used in Apple I-pod but it has a 15-degree angle mounting. I need either vertical or horizontal...
Hi,
Does anyone here have experience using AS2525 Telephone IC? Referring to attached datasheet, can pins DI, DO and CLK (refer to page 3) be interfaced to a uP to access and perform its programming settings (please refer to page 6 onwards, Table, 3, 4, 5 etc.).
Does anyone have and idea of...
Hi,
Does anyone here have a reference schematic for a typical telephone circuit. I have one using AS2540 but I need more sample schematic to have a more understanding regarding this.
Regards to all,
Howie
Hello,
Does anyone here have an idea on what SIM Card Interface IC to use and how to from sim card to processor. Do you have a suggested IC for this?
Any reference schematic regarding this??
Thanks.

Howie
Hi,
Can anybody give me idea regarding the cause of the diagonal noise seen on the image attached? This is the output from a camera input of a DVR. The noise are both experienced in VGA and RCA output.

Hi,
Anyone here who has an experience using a current transformer (CT), basically with a 5A maximum current intput.
Does anyone have an idea on what circuit to use in order to have a 0-5VDC linear output from 0-5A AC current input on the the CT? Can someone give me schematic/s regarding this...
Hi,
I have to convert the output of an AC current transformer (CT: 300A / 5A)into a 0-5VDC range for monitoring an AC current panel meter.
Can someone give me suggestions or schematics regarding this?
Regards,
Howie
Hello,
I need to monitor analog panel meters from a generator panel such as voltmeter and current meter (ammeter) that will be interfaced into uP. The voltage range is typically 0-250VAC and the current to be measured is within 5-600A range.
But the problem is I only have an ADC chip that...
You can use an ultrasonic-type of level meter. Its main technology uses sound waves that bounces back to a transducer from a measured surface (either solid or liquid surfaces). These devices have a lot of out interface options that can be connected into a micro controller. The device can come...
Hello guys,
Thank you for all your suggestions. I also believe that the problem is on the SHUTDOWN pin (SHDN, pin 14).
The following changes were performed (Refer to the attached schematic):
Case 1: I've tried Brian's idea to drive a 150-ohms load (R1731 from the attached schematic was...
MAX4315 - help needed
Anyone here who has an idea or reference schematic of MAX4315 (High-Speed, Low-Power, Single-Supply Multichannel, Video Multiplexer-Amplifiers).
I need this for DVR-SPOTOUT applications.
You can refer to attached datasheet.
Regards to all.
Thanks for your suggestion Kieth..
Let me explain the circuit attached above, Video inputs 1 to 8 (VIDEO_INPUT_CH1-8) are inputs from NTSC cameras and output is performed through SPOTOUT.
I already measured voltage from video input (pins 5 to 12) and it is within the of 0.035V - 2.2V, 1.05V...
_______
Thanks for your inputs..
Regarding suggestion "2", you indicated that the maximum input voltage should be "VCC-2.8". Does this mean 5.0 - 2.8 = 2.2V, So 2.2V must be the maximum VCC? Can you further expound on this? Where did you get 2.8VDC? Thanks..
Regards.
What seems to be the problem if the output from a video amplifier, MAX4315 to be specific, fades out as time increases. Meaning, video output from MAX4315 is clear upon Video input but as time elapses the pictures diminished.
I measured the waveform from the oscilloscope and it appeared that...
