SN65LVDS179-EP: Data speed when all buffers active

Part Number: SN65LVDS179-EP
Other Parts Discussed in Thread: SN65LVDS179

Hello team,

What would be the data speed for SN65LVDS179-EP, if all buffers are active?

On the datasheet for SN65LVDS179 (Non EP version), it says only 150Mbps when all buffers are active. Will it be the same for EP version?

Best Regards,
Kei Kuwahara

    The driver is faster than the receiver. The "all buffers" column assumes that you are using the same speed on all lines, so it just shows the minimum of the two other columns.

    The Mbps values are consistent with the propagation delays. The -EP driver has a longer worst-case propagation delay, which is probably caused only by the wider temperature range. So the maximum speed of the -EP is the same 150 Mbps.

    Hi Kei,

    The datasheet for the EP version does not specific a "maximum" table like the non-EP version does. 

    However, Figure 17 "Data Transmission Distance Versus Rate" plots the data out to 100M using different jitter values.

    This figure can be used as a guide to determine if the device will fit the customer application.

    Additionally, here is a helpful application note on the topic: How Far, How Fast Can You Operate LVDS Drivers and Receivers? (ti.com) 

    Thank you, Amy
