RHFLVDS228A Datasheet | STMicroelectronics

Features - LVDS input/output - Multiple configuration: Mux, repeater and splitter - ANSI TIA/EIA-644 pliant - 400 Mbps LVDS (200 MHz) - 200 MHz clock channel - Cold spare on all pins - Fail-safe function - 3.3 V operating power supply - 4.8 V absolute rating - Hermetic package - Power consumption: 220 m W at 3.3 V Description The RHFLVDS228A is an 8-channel, 4x4 crosspoint switch base, on low voltage differential signaling (LVDS) for low-power and high-speed munications. The two 4x4 multiplexers allow connection from any of the four inputs to any of the four outputs. Packaged and qualified for use in aerospace environments in a low-power, fast-transmission standard, the RHFLVDS228A operates at 3.3 V power supply (3.6 V max. operating and 4.8 V AMR) and a mon mode of -4 V to +5 V. The LVDS outputs operate over a controlled impedance of 100-ohm transmission media that may be printed circuit board traces, back planes, or cables. The circuit features an internal fail-safe function to ensure a known state in case of an input short circuit or a floating input. All pins have cold spare buffers to ensure they are in high impedance when VCC is tied to GND. The RHFLVDS228A can operate over a wide temperature range of -55 °C to +125 °C and it is housed in an hermetic Ceramic Flat-64 package. Table 1.
