The MAX9389 is a fully differential, high-speed, low-jitter, 8-to-1 ECL/PECL multiplexer (mux) with dual output buffers. The device is designed for clock and data distribution applications, and features extremely low propagation delay (310ps typ) and output-to-output skew (30ps max).
Three single-ended select inputs, SEL0, SEL1, and SEL2, control the mux function. The mux select inputs are compatible with ECL/PECL logic, and are internally referenced to the on-chip reference output (VBB1, VBB2), nominally VCC - 1.425V. The select inputs accept signals between VCC and VEE. Internal pulldowns to VEE ensure a low default condition if the select inputs are left open.
The differential inputs D_, D_ -bar can be configured to accept a single-ended signal when the unused complementary input is connected to the on-chip reference output (VBB1, VBB2). All the differential inputs have internal bias and clamping circuits that ensure a low output state when the inputs are left open.
The MAX9389 operates with a wide 2.375V to 5.5V supply range. The device is offered in 32-pin TQFP and thin QFN packages, and operates over the -40°C to +85°C extended temperature range.
