19-3915; Rev 1; 1/07 High-Bandwidth T1/E1 Dual-SPDT Switches/ 4:1 Muxes MAX4818/MAX4819 General Description Features The MAX4818/MAX4819 high-bandwidth, low-on-resis- Dual SPDT and 4:1 Multiplexer Configurations tance analog dual SPDT switches/4:1 multiplexers aredesigned to serve as integrated T1/E1 protection Dual-Supply Operation from ±3.3V to ±5V switches for 1+1 and N+1 line-card redundancy appli- Single-Supply Operation from +6V to +11V cations. Each MAX4818/MAX4819 replaces fourelectromechanical relays, significantly reducing board Hot-Insertion Tolerant with No DC Path to the space, simplifying PC board routing, and reducing Supplies power consumption. These devices operate with ±3.3V Low On-Resistance, RON = 4 (typ) and 6 (max) or ±5V dual supplies for applications requiring T1/E1signal switching in the line side of the interface trans- Over 350MHz -3dB Signal Bandwidth (MAX4818) former. Internal voltage multipliers drive the analog Excellent Crosstalk and Off-Isolation Performance switches, yielding excellent linearity and low 4 typicalon-resistance within the T1/E1 analog signal range. This Over the T1/E1 Signal Spectrum: Over 110dB high-bandwidth family of products is optimized for low Crosstalk Attenuation at 1MHz (MAX4818) return loss and matched pulse template performance in Low Current Consumption of 2mA (max) T1/E1 long-haul and short-haul applications. -40°C to +85°C Extended Temperature Range The MAX4818/MAX4819 are available in a tiny 16-pin,5mm x 5mm, thin QFN package and are specified over Space-Saving, 16-Pin, 5mm x 5mm Thin QFN the extended -40°C to +85°C temperature range.
