Part Number: HVDA551-Q1 Tool/software: Hi Expert,
Customer find HVDA551-Q1 CANH and CANL waveform jitter and the low level voltage is about 0.7V, which is higher than 0.5V. Every board has this issue, so this could be related to schematic and layout…
Part Number: HVDA551-Q1 Hi team,
when customer test HVDA551, they found CANH and CANL is abnormal, have a small voltage anomalies.
Could you please help analyze why this phenomenon occurs based on the following information.
Point-to-point communication…
Part Number: HVDA551-Q1 Hi Support Team.
A customer is considering this product as a replacement for another company's product and has requested an EMC TEST Report.
Could you please obtain the EMC TEST Report for HVDA551QDRQ1?
Thanks,
Yutaro H…
Part Number: HVDA551-Q1 Hi team,
I found that HVDA551 recommended Differential input voltage is -6~6V, because CANH and CANL of HVDA551 will exceed 6V when doing EMC test, could you pls help share the HVDA551 Max differential voltage between CANH and CANL…
Part Number: TCAN844-Q1 Other Parts Discussed in Thread: TCAN844V-Q1 Tool/software: Hi Expert,
VDIFF is -120mV ~+12mV for TCAN844V-Q1. What’s the advantage compared to HVDA551, which is -12mV ~+12mV?
Part Number: HVDA551-Q1 Hi team,
My customer is using HVDA551QDRQ1. The other side of HVDA551 is a PLC and the terminal resistor is 120 ohm. HVDA551 VCC=5V and VIO=3.3V.
When HVDA551 is sending data out, we measured its differential output voltage between…
Part Number: HVDA551-Q1 On the datasheet, there are two particular features listed:
- Data rate up to 1Mbps
- Supports Can Flexible Data-Rate (FD)
Does the latter imply that the transceiver can accept CAN-FD messages with payloads of up to 64 bytes? Or…
Part Number: SN65HVD1050 Other Parts Discussed in Thread: HVDA551-Q1 Hi team,
When my customer used HVD1050 for surge test, he found that when CANH and CANL add negative 2kV surge to ground, HVD1050 will be damaged, and the impedance of CANH and CANL to…
Part Number: HVDA551-Q1 Hi Team,
Do we have maximum rise and fall time of HVDA551-Q1 differential output signal can share with the customer? The datasheet only mentioned the typical value of these specs.
Best Regards,
