MAX9152

19-2003; Rev 0; 4/01 800Mbps LVDS/LVPECL-to-LVDS 2 x 2 Crosspoint Switch General Description The MAX9152 2 x 2 crosspoint switch is designed for applications requiring high speed, low power, and lownoise signal distribution. This device includes two LVDS/LVPECL inputs, two LVDS outputs, and two logic inputs that set the internal connections between differential inputs and outputs. The MAX9152 can be programmed to connect any input to either or both outputs, allowing it to be used in the following configurations: 2 ✕ 2 crosspoint switch, 2:1 mux, 1:2 demux, 1:2 splitter, or dual repeater. This flexibility makes the MAX9152 ideal for protection switching in fault-tolerant systems, loopback switching for diagnostics, fanout buffering for clock/data distribution, and signal regeneration for communication over extended distances. Ultra-low 120psPK-PK (max) PRBS jitter ensures reliable communications in high-speed links that are highly sensitive to timing error, especially those incorporating clock-and-data recovery, or serializers and deserializers. The high-speed switching performance guarantees an 800Mbps data rate and less than 50ps (max) skew between channels. LVDS inputs and outputs are compatible with the TIA/EIA-644 LVDS standard. The LVDS inputs are designed to also accept LVPECL signals directly, and PECL signals with an attenuation network. The LVDS outputs are designed to drive 75Ω or 100Ω loads, and feature a selectable differential output resistance to minimize refle...
