FSA641 — 2:1 MIPI Switch, Featuring 2-Data and 1-Data
Lane Configuration
Features
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 (CON) of 8 pF. The wide bandwidth (1 GHz)
results in signals with minimum edge and phase
distortion.
Superior
channel-to-channel
crosstalk
minimizes interference.

Pin Configuration
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable
above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition,
extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute
maximum ratings are stress ratings only.
