Update: 30 September, 2023
The MAX9325 low-skew, 2:8 differential driver features extremely low output-to-output skew (50ps max) and part-to-part skew (225ps max). These features make the device ideal for clock and data distribution across a backplane or board. The device selects one of the two differential HSTL or LVECL/LVPECL inputs and repeats them at eight differential outputs. Outputs are compati- ble with LVECL and LVPECL, and can directly drive 50Ω terminated transmission lines. The differential inputs can be configured to accept a single-ended signal when the unused complementary input is connected to the on-chip reference output volt- age VBB. All inputs have internal pulldown resistors to VEE. The internal pulldowns and a fail-safe circuit ensure differential low default outputs when the inputs are left open or at VEE. The MAX9325 operates over a 2.375V to 3.8V supply range for interfacing to differential HSTL and LVPECL signals. This allows high-performance clock or data dis- tribution in systems with a nominal +2.5V or +3.3V sup- ply. For LVECL operation, the device operates with a -2.375V to -3.8V supply. The MAX9325 is offered in 28-lead PLCC and space- saving 28-lead QFN packages. The MAX9325 is speci- fied for operation from -40°C to +85°C.
