Part Number: LMH1228
Hello Support team,
I could find below description regarding SMBus address pins.
Could you let me know the timing definition to read ADDR[1:0] at power up process?
If you can show the timing chart with voltage level of VIN, it is…
Part Number: LMH1228 Other Parts Discussed in Thread: LMH1208 Hello,
Our customer complained he could not down load the programming guide (SNAU206) from the web site, even though he had accessed the down load site.
Could you kindly help him to down load…
Part Number: LMH1228 Hello Support team,
In case of "ENABLE"=H (open), is the output signal state at "SDI_OUT" immediately stable after entering input signal to "IN0+/-"?
Is there any delay time for achieving the stable output…
Part Number: LMH1228 Other Parts Discussed in Thread: LMH1297 Dear Team,
we are currently routing a layout with the LMH1228. The traces would run much smoother if we could exchange/swap the + and - pins of the differential interface: swap IN+ with IN0…
Part Number: LMH1228 Hi team,
My customer is designing with LMH1228 and needs help on software setting.
Could you please take a look below?
The Programming guide (SNAU206C) section 3.1.1 shows resistor configuration example.
In the 4 th step: read 0xFE…
Part Number: LMH1228 Hi team,
Could you please share how to configure resistor setting for measuring return loss?
Also, if there is any precaution on return loss measurements or related material (e.g. application note), please let me know.
Best regards…
Part Number: LMH1228 Other Parts Discussed in Thread: LMH1297 Hi team,
My customer is going to test the 12G SDI return loss. Could you please advise me on the following?
<Premise> It is a system that outputs single end from SDO_OUT1.
<Question>…
Part Number: LMH1228 Hello Support team,
According to datasheet P3, SDI_OUT1– should be similarly AC-coupled and terminated with an external 4.7-μF capacitor and 75-Ω resistor to GND.
Is it possible to use SDI_OUTx+/- as differential lines…
Part Number: LMH1208 Other Parts Discussed in Thread: LMH1297 , LMH1226 , LMH1219 , LMH1218 , LMH1228 Tool/software: We are being asked to design a 3U 160 mm card with e 75-ohm BNC to 100-differential convertor. The signal speed is 3G to 12G The distance…
Part Number: LMH1228 I have an FPGA driving the LMH1228. jitter is fine at higher bit rates, but at 270Mb SD it is large.
Most of the SD jitter is reasonable +-250ps, but see occasional spikes to +-600, so the jitter is out of spec.
The spikes seem to…
