MAXP-37161B 16 Channel, 28 Gbps Crosspoint Switch & Signal Conditioner Rev V1 Low Power Operation Features Single 1.8 V Power Supply (DV 3.3V optional for digital interface) 16-channel Crosspoint Switch with CDRs and Signal Conditioners DDIO Extended operating temperature range: -40C to +85 C Five-Tap Decision Feedback Equalizer (DFE) Applications Adaptive Continuous Time Linear Equalizer (ADCTLE) Storage Area Network Switch Fabrics Individual lane LOS (Loss of Signal) detection and squelch Reconfigurable Optical Add-Drop Multiplexer Switch CDRs support different data rates with a single reference clock Multirate Linecard Redriver & Retimer, Multirate Switch Fabric Integrated Non-Blocking Crosspoint Switches Backplane Signal Conditioning for 100 GE, EDR InfiniBand, Programmable Output Swing with Pre and Post De-Emphasis Levels 32 G FibreChannel Four Eye Monitors for input jitter diagnostics Front Panel Retimer for (4x25G) Modules and Copper Four PRBS-31 pattern generators and checkers The MAXP-37161 is a highly integrated, low power fully non-blocking crosspoint switch designed to compensate for lossy backplane channels at rates of 100Mbps up to 28.1Gbps. The MAXP-37161 is comprised of a 16-channel crosspoint switch core with CDRs that are able to re-time data rates from 2.4 Gbps up to 28.1 Gbps and thus eliminate residual jitter and provide a clean signal for transmitting to downstream devices. Each input buffer offers a Decision Feedback Equalization (DFE) or an Adaptive Continuous Time Linear Equalization (ADCTLE) that aids to compensate up to 32 dB of insertion loss at 25.78 Gbps. Each channel can be independently setup to run at different data rates if needed. Each output buffer has a three-tap Finite Impulse Response (FIR) filter De-emphasis that help to pre-compensate for channel losses between the MAXP-37161 and any downstream devices. Diagnostic features are also available, including four integrated PRBS generators/checkers and four on-chip eye monitors for in-service link margin evaluation and/or receiver optimization. 2 The MAXP-37161 can be controlled via a standard two-wire I C compatible, four-wire SPI with daisy-chain support and MDIO interface for host control. The MAXP-37161 is packaged in a 196-pin, 15 mm x 15 mm BGA package.
