Part Number: TIDA-01365 Other Parts Discussed in Thread: TLC555 Hello
Can I set the pulse duration of TLC555 to 80us in RS-485 Bidirectional Fan-Out Hub?
C10 : 0.47uF -> 0.012uF
T = 1.1 x 6.19K x 0.012uF
T = 81.708us
Best regards.
Part Number: TIDA-01365 My design will be a single input, three output rather than the four output shown in TIDA-01365. While I create any problems if I do not populate the fourth slave device circuitry?
Part Number: TIDA-01365 Other Parts Discussed in Thread: SN65HVD3082E Regarding the design shown in TIDA-01365: Can you please explain why the pull up/pull down resistors are not required? This would be R2/R5, R9/R16, R18/R20, R4/R11.
Karthik,
You can find the information in this design guide. The cable type is covered in section 5, topology in section 3, stub length in section 6.

I'm not sure what kind of fan-out you refer to. This TI design might interest…
Gil,
I think your solution is straightforward and should work fine. You can refer to this TI design with the similar function.

However, I'm not sure if you could just connect the full duplex TX and RX pair together to communicate…
Hi Tulika,
You want to place a repeater somewhere along this differential bus so that it re-drives the differential signaling going in both directions, right? If so, you could reference this circuit:

It is designed to repeat…
Hi Mo,
In general, RS-422 signals are typically terminated at the furthest end of the transmission cable using a shunt resistance between the two lines making up the balanced differential pair. The resistance is typically chosen so that it matches the…
Hi Rahul,
SN65HVD63 could directly interface to an RS-485 transceiver like SN65HVD72 or SN65HVD82 (depending on which VCC level is needed) via the TXIN, RXOUT, and DIR pins. That seems like the most straightforward solution. The other option is to…
Hi Carlo,
Thanks for posting your question on E2E. It is an interesting question.
For the fanout, are you talking about an application like this?

The way the fanout is implemented will have it's own set of limits to…
Christoph,
If you follow this reference design, the transceivers can be any general 8pin RS485 devices, like HVD82, HVD3082.

TI has USB hubs. www.ti.com/.../hubs-products.page
But I’m not familiar with USB spec. That’s just another…
