MAX9152 19-2003 Rev 0 4/01 800Mbps LVDS/LVPECL-to-LVDS 2 x 2 Crosspoint Switch General Description Features The MAX9152 2 x 2 crosspoint switch is designed for Pin-Programmable Configuration applications requiring high speed, low power, and low- 2 x 2 Crosspoint Switch noise signal distribution. This device includes two 2:1 Mux LVDS/LVPECL inputs, two LVDS outputs, and two logic 1:2 Demux inputs that set the internal connections between differ- 1:2 Splitter ential inputs and outputs. Dual Repeater The MAX9152 can be programmed to connect any Ultra-Low 120ps (max) Jitter with 800Mbps, PK-PK input to either or both outputs, allowing it to be used in 23 PRBS = 2 -1 Data Pattern the following configurations: 2 2 crosspoint switch, 2:1 mux, 1:2 demux, 1:2 splitter, or dual repeater. This flexi- Low 50ps (max) Channel-to-Channel Skew bility makes the MAX9152 ideal for protection switching 109mW Power Dissipation in fault-tolerant systems, loopback switching for diag- nostics, fanout buffering for clock/data distribution, and Compatible with ANSI TIA/EIA-644 LVDS Standard signal regeneration for communication over extended Inputs Accept LVDS/LVPECL Signals distances.

The high-speed switching performance guarantees (SO Package) an 800Mbps data rate and less than 50ps (max) skew Available in 16-Pin TSSOP Package between channels. (Half the Size of SO) LVDS inputs and outputs are compatible with the TIA/EIA-644 LVDS standard. The LVDS inputs are Ordering Information designed to also accept LVPECL signals directly, and PART TEMP. RANGE PIN-PACKAGE PECL signals with an attenuation network. The LVDS MAX9152ESE -40C to +85C 16 SO outputs are designed to drive 75 or 100 loads, and MAX9152EUE -40C to +85C 16 TSSOP feature a selectable differential output resistance to minimize reflections. Pin Configuration appears at end of data sheet. The MAX9152 is available in 16-pin TSSOP and SO packages, and consumes only 109mW while operating from a single +3.3V supply over the -40C to +85C Functional Diagram temperature range.
