SLLS902A February 2010 – March 2024 SN65MLVD040
PRODUCTION DATA
The SN65MLVD040 family of products offered by Texas Instruments provides a glitch-free powerup/down feature that prevents the M-LVDS outputs of the device from turning on during a powerup or powerdown event. This is especially important in live insertion applications, when a device is physically connected to an M-LVDS multipoint bus and VCC is ramping.
While the M-LVDS interface for these devices is glitch free on powerup/down, the receiver output structure is not. Figure 7-2 shows the performance of the receiver output pin, R (CHANNEL 2), as VCC (CHANNEL 1) is ramped.
The glitch on the R pin is independent of the RE voltage. Any complications or issues from this glitch are resolved in power sequencing or system requirements that suspend operation until VCC has reached a steady state value.
