MAX9392/MAX9393 19-2913 Rev 1 5/07 Anything-to-LVDS Dual 2 x 2 Crosspoint Switches General Description Features The MAX9392/MAX9393 dual 2 x 2 crosspoint switches 1.5GHz Operation with 250mV Differential Output perform high-speed, low-power, and low-noise signal Swing distribution. The MAX9392/MAX9393 multiplex one of two 2ps (max) Random Jitter RMS differential input pairs to either or both low-voltage differ- AC Specifications Guaranteed for 150mV ential signaling (LVDS) outputs for each channel. Differential Input Independent enable inputs turn on or turn off each differ- ential output pair. Signal Inputs Accept Any Differential Signaling Standard Four LVCMOS/LVTTL logic inputs (two per channel) con- trol the internal connections between inputs and outputs. LVDS Outputs for Clock or High-Speed Data This flexibility allows for the following configurations: 2 x 2 High-Level Input Fail-Safe Detection (MAX9392) crosspoint switch, 2:1 mux, 1:2 splitter, or dual repeater. Low-Level Input Fail-Safe Detection (MAX9393) This makes the MAX9392/MAX9393 ideal for protection switching in fault-tolerant systems, loopback switching for 3.0V to 3.6V Supply Voltage Range diagnostics, fanout buffering for clock/data distribution, LVCMOS/LVTTL Logic Inputs Control Signal and signal regeneration. Routing Fail-safe circuitry forces the outputs to a differential low condition for undriven inputs or when the common- Ordering Information mode voltage exceeds the specified range.
