Hello,
I am having some issues when interfacing to a camera PAL video signal where the first 5 sync amplitudes at the start of each field are about 40mV higher than subsequent syncs.
I note that the Electrical Characteristics table, on page 3 of the data…
Other Parts Discussed in Thread: LMH1981 , DS90LV019 , DS90LT012A , DS91C180 , SN65MLVD204A Hi,
Customer is considering line transceiver, or driver and receiver for LMH1981 outputs. I have attached system configuration diagram.
Their system is 4k transmission…
Other Parts Discussed in Thread: LMH1981 Dear Sir / Madam,
We have few questions regarding to LMH1981
1 . In Datasheet, all timing Value(s) are Typical, no min. no Max.
We would like to get Min and Max, or at least Max timing parameters.
For example…
Other Parts Discussed in Thread: LMH1983 , LMH1981 PART NAME : LMH1983, LMH1981
Dear TI Circuit Engineer
Hello, I am a researcher working as a circuit engineer at LG Electronics.
I made a circuit with LMH1983 and LMH1981 and FPGA ICs, and I would like to…
Other Parts Discussed in Thread: LMH1981 Hello,
I have a question regarding the Odd and Even output. In the datasheet, on page 15, it is assumed that the first field of the frame is odd. While in some other resources the first field is even which is followed…
Hi Derek,
Thanks for the support. I have two questions for the application with LMH1981 and LMH1983 as below.
LMH1981 have 6 outputs OEOUT/BPOUT/CSOUT/VFOUT/VSOUT/HSOUT and the application only use three HVF of them to LMH1983. I wonder what's the application…
Other Parts Discussed in Thread: LMH1982 The datasheet says to add 100ohm series resistors for current limiting.
The lmh1982 eval kit has 50ohm resistors on these lines.
Which is correct and why are the resistors spec'd on these lines? How much different…
Other Parts Discussed in Thread: LMH1981 Are the VSout and HSout pins are driven differently than the OEout or VFout, etc. Scope shots show quite a difference in these nets. That and the Ibis model is a different output driver for the HSout pin.
