Maxim Integrated MAX9122

The MAX9122 features integrated parallel termination resistors (nominally 107Ω), which eliminate the requirement for four discrete termination resistors and reduce stub lengths. The MAX9121 inputs are high impedance and require an external termination resistor when used in a point-to-point connection. The devices support a wide common-mode input range of 0.05V to 2.35V, allowing for ground potential differences and common-mode noise between the driver and the receiver.

GENERAL DESCRIPTION

The MAX9121/MAX9122 quad low-voltage differential signaling (LVDS) differential line receivers are ideal for applications requiring high data rates, low power, and low noise. The MAX9121/MAX9122 are guaranteed to receive data at speeds up to 500Mbps (250MHz) over controlledimpedance media of approximately 100Ω. The transmission media may be printed circuit (PC) board traces or cables. The MAX9121/MAX9122 accept four LVDS differential inputs and translate them to LVCMOS outputs. A fail-safe feature sets the output high when the inputs are open, or when the inputs are undriven and shorted or parallel terminated. The EN and EN inputs control the high-impedance output. The enables are common to all four receivers. Inputs conform to the ANSI TIA/EIA644 LVDS standard. Flow-through pinout simplifies PC board layout and reduces crosstalk by separating the LVDS inputs and LVCMOS outputs. The MAX9121/ MAX9122 operate from a single +3.3V supply, and are specified for operation from -40°C to +85°C.
