Other Parts Discussed in Thread: LMH1982 , LMH1983 Is it possible to program the LMH1982 to generate a 29.5MHz clock when genlocked to a PAL video signal, and to generate a 24.546MHz clock when genlocked to a NTSC signal?
These clock signals allow me to…
Other Parts Discussed in Thread: LMH1982LMH1982 Application If the input format is 625i and the output format 1080i/50 ,then how to program the register and what is the programming sequence?
Other Parts Discussed in Thread: LMH1983 , LMH1982 Both LMH1982 and LMH1983 have LVDS clock outputs.
These output clock may be DC coupled to differential inputs of FPGAs with 2.5V power rail. My concern is that if LVDS output may higher than 2.5V signal…
Part Number: LMH1982SQEEVAL Other Parts Discussed in Thread: LMH1982 Hi I bought a LMH1982 evaluation board. I connected it to a PC, but I can't get any detection message, at most I'm getting a "Not recognized USB device". I tried it with 3 computers, 2…
Other Parts Discussed in Thread: LMH1982 Please tell me how LMH1982 detects H_ERROR.
When (Hsync input / reference divider) and (VCXO clock / feedback divider) has phase error, there should be some "threshold" or "Time Window" for LMH1982 to decide the…
I understand the "LOCK_CTRL" (Register 01h) programs the maximum phase error between PLL1's Phase Detector inputs.
Is the allowable phase error set by LOCK_CTRL based on (Hsync input / reference divider) or (VCXO clock / feedback divider…
Hi Anil,
FPGA provides LVDS TX clock for LMH0340 - please refer to the LMH0340 data sheet for TX clock details. LMH1982 uses reference clock - such as black burst - and provides video/audio clocks to the FPGA. LMH1982 is not providing clock to the LMH0340…
Part Number: LMH1981 Other Parts Discussed in Thread: LMH1982 , I use the LMH1981 sync separator to pass HSOUT, VSOUT and FOUT to my FPGA. These signals are then fed through to the LMH1982. From time to time the LMH1982 loses reference, because there are…
