Low-Voltage, High-Isolation, Dual 4-Channel RF/Video Multiplexer
General Description
The MAX4588 low-voltage, dual 4-channel multiplexer is designed for RF and video signal processing at frequencies up to 180MHz in 50Ω and 75Ω systems. A flexible digital interface allows control of on-chip functions through either a parallel interface or an SPI™/ MICROWIRE™ serial port. Each channel of the MAX4588 is designed using a “T” switch configuration, ensuring excellent high-frequency off-isolation. The MAX4588 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). The offleakage current is under 1nA at TA = +25°C, and less than 10nA at TA = +85°C.
