Customer is evaluating SN65LVDS388A for single end output, but start to supply vcc and occur 5V-overshoot.
⇒device is damaged.
Schematic and waveform is attached below;
※Single end is not output(35 pin), Differencial input pin(1pin-2pin) are Open.
※Single end is output(32 pin), Differencial input pin(6pin-7pin) are Open.
Please let me know about three points below.
①I think that one of cause is Vcc inlush for fast startup.
Is there recommended spec for Vcc start up time?
②In fact, the above differencial input circuit is no connect to transmitter. (100Ω termination is connecting)
Is these circuit no problem?
③If there find the other cause, please let me know.
Best regards,
Satoshi
