Description
The FSA641 is a 2:1 MIPI switch made for 2-data lane and
1-data lane modules. This part is configured as a single-
pole, double-throw switch (SPDT) and is optimized for
switching between two high-speed or low-power MIPI
sources. The FSA641 has specially been designed for the
MIPI specification and allows connection to either a CSI or
DSI module. The FSA641 features an extremely low on
capacitance (C_ON) of 8 pF. The wide bandwidth (1 GHz)
results in signals with minimum edge and phase distortion.
Superior channel-to-channel crosstalk minimizes
interference.
