They are pin-compatible speed up- • Pin-Compatible With SN65LVDS22 and grades to the SN65LVDS22 and SN65LVDM22. The SN65LVDM22 internal signal paths maintain differential signaling for • 25 mV of Receiver Input Threshold Hysteresis high speeds and low signal skews. These devices Over 0-V to 4-V Common-Mode Range have a 0-V to 4-V common-mode input range that accepts LVDS, LVPECL, or CML inputs. Two logic • Inputs Electrically Compatible With CML, pins (S0 and S1) set the internal configuration be- LVPECL and LVDS Signal Levels tween the differential inputs and outputs. This allows • Propagation Delay Times, 900 ps Maximum the flexibility to perform the following configurations: • LVDT Integrates 110- Ω Terminating Resistor 2 x 2 crosspoint switch, 2:1 input multiplexer, 1:2 splitter or dual repeater/translator within a single • Offered in SOIC and TSSOP device. Additionally, SN65LVDT122 incorporates a 110- Ω termination resistor for those applications where board space is a premium. Although these • 10-G (OC-192) Optical Modules devices are designed for 1.5 Gbps, some applications • 622-MHz Central Office Clock Distribution at a 2-Gbps data rate can be supported depending on loading and signal quality. • Wireless Basestations • Low Jitter Clock Repeater/Multiplexer The intended application of this device is ideal for loopback switching for diagnostic routines, fanout • Protection Switching for Serial Backplanes buffering of clock/data distribution provide protection in fault-tolerant systems, clock multiplexing in optical modules, and for overall signal boosting over extended distances.
