AD8151

FEATURES Low cost 33 × 17, fully differential, nonblocking array 3.2 Gbps per port NRZ data rate Wide power supply range: +3.3 V, –3.3 V Low power 425 mA (outputs enabled) 35 mA (outputs disabled) LV PECL- and LV ECL-compatible CMOS/TTL-level control inputs: 3 V to 5 V Low jitter No heat sinks required Drives a backplane directly Programmable output current Optimize termination impedance User-controlled voltage at the load Minimize power dissipation Individual output disable for busing and reducing power Double row latch Buffered inputs 184-lead LQFP package GENERAL DESCRIPTION The AD81511 is a member of the Xstream line of products, offering a breakthrough in digital switching and a large switch array (33 × 17) on very little power—typically less than 1.5 W. It also operates at data rates in excess of 3.2 Gbps per port, making it suitable for Sonet OC-48 applications with 8/10-bit forward-error correction (FEC). Furthermore, the price of the AD8151 makes it affordable enough to be used for lower data rates. The AD8151’s flexible supply voltages allow the user to operate with either emitter-coupled logic (ECL) or positive emitter-coupled logic (PECL) data levels, and with 3.3 V for further power reduction. The control interface is CMOS/TTL-compatible (3 V to 5 V). Its fully differential signal path reduces jitter and crosstalk, while allowing the use of smaller, single-ended voltage swings. The AD8151 is offered in a 184-lead LQFP package that operates over the extended comme...
