MAX9129
Quad Bus LVDS Driver with Flow-Through Pinout
|
Status
Active: In Production.
Description
The MAX9129 is a quad bus low-voltage differential signaling (BLVDS) driver with flow-through pinout. This device is designed to drive a heavily loaded multipoint bus with controlled transition times (1ns 0% to 100% minimum) for reduced reflections. The MAX9129 accepts four LVTTL/LVCMOS input levels and translates them to output levels of 250mV to 450mV (standard LVDS levels) into a 27Ω load at speeds up to 200Mbps (100MHz).
The power-on reset ensures that all four outputs are disabled and high impedance during power up and power down. The outputs can be set to high impedance by two enable inputs, EN and active-low EN, thus dropping the device to a low-power state of 11mW. The enables are common to all four drivers. The flow-through pinout simplifies PC board layout and reduces crosstalk by keeping the LVTTL/LVCMOS inputs and BLVDS outputs separated.
The MAX9129 operates from a single +3.3V supply and is specified for operation from -40°C to +85°C. It is available in 16-pin QFN and TSSOP packages. Refer to the MAX9121 data sheet for a quad LVDS line receiver with flow-through pinout.
