Low-
Voltage, High-Isolation, Dual 2-Channel RF/Video Multiplexer
General Description
The MAX4589 low-
voltage, dual 2-channel multiplexer is designed for RF and video signal processing at frequencies up to 200MHz in 50Ω and 75Ω systems.
On-chip functions are controlled through either a parallel interface or an SPI™/QSPI™/MICROWIRE™ serial interface.
Each channel of the MAX4589 is designed using a “T” switch configuration, ensuring excellent high-frequency off-isolation.
The MAX4589 has low on-resistance of 60Ω max, with an on-resistance match across all channels of 4 Ω max.
Additionally, on-resistance is flat across the specified signal range (2Ω max).
