Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX9392/MAX9393 dual 2 x 2 crosspoint switches perform high-speed, low-power, and low-noise signal distribution. The MAX9392/MAX9393 multiplex one of two differential input pairs to either or both low-voltage differential signaling (LVDS) outputs for each channel. Independent enable inputs turn on or turn off each differential output pair.

Four LVCMOS/LVTTL logic inputs of MAX9393 (two per channel) control the internal connections between inputs and outputs. This flexibility allows for the following configurations: 2 x 2 crosspoint switch, 2:1 mux, 1:2 splitter, or dual repeater. This makes the MAX9392/MAX9393 ideal for protection switching in fault-tolerant systems, loopback switching for diagnostics, fanout buffering for clock/data distribution, and signal regeneration.

Fail-safe circuitry of MAX9393 forces the outputs to a differential low condition for undriven inputs or when the commonmode voltage exceeds the specified range. The MAX9392 provides high-level input fail-safe detection for LVDS, HSTL, and other GND-referenced differential inputs. The MAX9393 provides low-level input fail-safe detection for LVPECL, CML, and other VCC-referenced differential inputs.

Ultra-low 98ps(P-P) (max) pseudorandom bit sequence (PRBS) jitter of MAX9393 ensures reliable communications in highspeed links that are highly sensitive to timing error, especially those incorporating clock-and-data recovery, or serializers and deserializers. The high-speed switching performance guarantees 1.5GHz operation and less than 67ps (max) skew between channels.

LVDS inputs and outputs are compatible with the TIA/EIA-644 LVDS standard. The LVDS outputs drive 100 loads. The MAX9392/MAX9393 are offered in 5mm x 5mm thin QFN with exposed paddle and 32-pin TQFP packages and operate over the extended temperature range (-40°C to +85°C).
