Any of its 68 differential w Power down of individual output drivers LVPECL input signal pairs can be connected to any DEVICE SPECIFICATION Parallel read back function LVTTL configuration controls Internal 100 Ω line to line terminations on high-speed differential inputs Reconfigurable without disturbing operation Single +3.3 V supply or +2.5 V supply 9.5 W typical power dissipation with 800 mV output swing Compact 32.5 mm x 32.5 mm 624 pin CBGA package Complies with Bellcore and ITU-T standards or all of its 69 differential CML output signal pairs. The differential logic data path makes the part ideal for high-speed applications. The differential nature of the data path is retained throughout the crosspoint structure to minimize data distortion and to handle NRZ data rates up to 3.2 Gbps. The high-...
