Eye Pattern of Two Outputs
Operating Simultaneously
The SN65LVDS125A and SN65LVDT125A are 4x4
nonblocking
crosspoint
switches.
Low-voltage
differential signaling (LVDS) is used to achieve
signaling rates of 1.5 Gbps per channel. Each output
driver includes a 4:1 multiplexer to allow any input to
be routed to any output. Internal signal paths are fully
differential to achieve the high signaling speeds while
maintaining low signal skews. The SN65LVDT125A
incorporates 110-Ω termination resistors for those
applications where board space is a premium.
Designed to support signaling rates up to 1.5 Gbps
for OC-12 clocks (622 MHz). The 1.5-Gbps signaling
rate allows use in HDTV systems, including SMPTE
292 video applications requiring signaling rates of
1.485 Gbps.
The SN65LVDS125A and SN65LVDT125A
characterized for operation from -40°C to 85°C.

tsk(p) is the magnitude of the time difference between the tPLH and tPHL of any output of a single device.
tsk(o) is the maximum delay time difference between drivers over temperature, VCC, and process.
tsk(pp) is the magnitude of the difference in propagation delay times between any specified terminals of two devices when both devices
operate with the same supply voltages, at the same temperature, and have identical packages and test circuits.
Jitter specifications are based on design and characteriztion. Stimulus system jitter of 1.9 ps tjit(per), 16 ps tjit(cc). 17 ps tjit(pp), and 7.2 ps
tjit(det) have been subtracted from the values.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
