www.DataSheet4U.com 19-3915; Rev 1; 1/07 High-Bandwidth T1/E1 Dual-SPDT Switches/ 4:1 Muxes General Description The MAX4818/MAX4819 high-bandwidth, low-on-resistance analog dual SPDT switches/4:1 multiplexers are designed to serve as integrated T1/E1 protection switches for 1+1 and N+1 line-card redundancy applications. Each MAX4818/MAX4819 replaces four electromechanical relays, significantly reducing board space, simplifying PC board routing, and reducing power consumption. These devices operate with ±3.3V or ±5V dual supplies for applications requiring T1/E1 signal switching in the line side of the interface transformer. Internal voltage multipliers drive the analog switches, yielding excellent linearity and low 4Ω typical on-resistance within the T1/E1 analog signal range. This high-bandwidth family of products is optimized for low return loss and matched pulse template performance in T1/E1 long-haul and short-haul applications. The MAX4818/MAX4819 are available in a tiny 16-pin, 5mm x 5mm, thin QFN package and are specified over the extended -40°C to +85°C temperature range. Features ♦ Dual SPDT and 4:1 Multiplexer Configurations ♦ Dual-Supply Operation from ±3.3V to ±5V ♦ Single-Supply Operation from +6V to +11V ♦ Hot-Insertion Tolerant with No DC Path to the Supplies ♦ Low On-Resistance, RON = 4Ω (typ) and 6Ω (max) ♦ Over 350MHz -3dB Signal Bandwidth (MAX4818) ♦ Excellent Crosstalk and Off-Isolation Performance Over the T1/E1 Signal Spectrum: Over 110dB Crosstalk Attenuation at 1MHz (MAX4818) ♦ Low Current Consumption of 2mA (max) ♦ -40°C to +85°C Extended Temperature Range ♦ Space-Saving, 16-Pin, 5mm x 5mm Thin QFN ♦ SET Controls All Switches Simultaneously For Redundancy Switching (MAX4819) MAX4818/MAX4819 Applications T1/E1 Redundancy Switching Base Stations and Base-Station Controllers Add and Drop Multiplexers Pin Configurations NC1 V+ TOP VIEW NC2 9 N.C. 10 Multi-Service Provisioning Platforms Edge Routers Multi-Service-Switches (MSSs) Digital Loop Carriers Industrial Applications Data Acquisition Telecom Signal Switching Test Equipment Avionics 12 11 COM1 IN1 SET N.C. 13 14 8 7 COM2 IN2 EN N.C.
