General Description
The MAX9360/MAX9361 are low-skew, single LVTTL/ TTL/CMOS-to-differential LVECL/ECL translators designed for high-speed signal and clock driver appli­cations. For interfacing to LVTTL/TTL/CMOS input sig­nals, these devices operate over a 3.0V to 5.5V supply range, allowing high-performance clock or data distrib­ution. For interfacing to differential LVECL/ECL output signals, these devices operate from a -2.375V to -5.5V supply.
The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL translator that operates at a typical speed of 3GHz. The MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator that operates at a typical speed of 1.3GHz. Both devices can be used to drive either LVECL devices or standard ECL devices with a negative supply range of
-2.375V to -5.5V.

Detailed Description
The MAX9360/MAX9361 are low-skew, single LVTTL/ CMOS/TTL-to-differential LVECL/ECL translators designed for high-speed signal and clock driver appli­cations. For interfacing to LVTTL/TTL/CMOS input sig­nals, these devices operate over a 3.0V to 5.5V supply range, allowing high-performance clock or data distrib­ution in systems with a nominal 3.3V or 5.0V supply. For interfacing to differential LVECL/ECL output signals, these devices operate from a -2.375V to -5.5V supply.
The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL translator that operates at typical speeds of 3GHz. The MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator that operates at typical speeds of 1.3GHz. Both devices can be used to drive either LVECL devices or standard ECL devices with a negative supply range of -2.375V to -5.5V.
Input
The MAX9360/MAX9361 inputs accept standard LVTTL/ TTL/CMOS levels. The input has pullup circuitry that dri­ves the outputs to a differential high if the inputs are open.
Differential Output
Output levels are referenced to GND and are considered ECL or LVECL, depending on the level of the VEEsupply. With GND connected to zero and VEEat -4.2V to -5.5V, the outputs are ECL. The outputs are LVECL when GND is connected to zero and VEEis at -2.375V to -3.8V.
Applications Information
Supply Bypassing
Bypass VCCand VEEto ground with high-frequency surface-mount ceramic 0.1µF and 0.01µF capacitors in parallel as close as possible to the device, with the
0.01µF value capacitor closest to the device. Use multi­ple parallel vias for low inductance.
Traces
Input and output trace characteristics affect the perfor­mance of the MAX9360/MAX9361. Connect each signal of a differential output to a 50Ω characteristic imped­ance trace. Minimize the number of vias to prevent impedance discontinuities. Reduce reflections by main­taining the 50Ω characteristic impedance through con­nectors and across cables. Reduce skew within a differential pair by matching the electrical length of the traces.
On the MAX9360, if the input edge rate approaches the electrical length of the interconnect, then controlled­impedance transmission lines should be used for the input traces.
Output Termination
Terminate outputs through 50Ω to -2V or use an equiva­lent Thevenin termination. Terminate both outputs and use the same termination on each for the lowest output­to-output skew. When a single-ended signal is taken from a differential output, terminate both outputs. For example, if Q is used as a single-ended output, termi­nate both Q and Q.
Ensure that the output currents do not exceed the con­tinuous safe output current limit or surge output current limit as specified in the
Absolute Maximum Ratings
table. Under all operating conditions, the device’s total thermal limits should be observed.
