An electrical connector (1) includes an insulative housing (10), a number of terminals (20) and a shielding shell. The housing includes a body portion, (11), a mating portion (12) extending forwardly from the body portion and a number of passageways (124) defined therein. The terminals includes a number of digital signal, power, grounding and analog signal terminals (221, 222, 223). The terminals have four groups (21, 22, 23, 24) arrayed in rows. The group (22) of terminals includes three analog signal terminals. The distance between the adjacent two analog signal terminals is twice the distance between adjacent two other types of terminals except the analog signal terminals, thereby reducing variation range of characteristic impedance of the connector.
