In this paper, a new family (r) of 2n binary sequences of period 2n-1 is proposed, where n≡2 mod 4 and gcd (r, 2n/2-1)=1. The presented family takes 4-valued out-of-phase auto- and cross-correlation values -1, ±2n/2-1, and 2n/2+1-1, and its correlation distribution is determined. For r=2(n-2)/4-1, each sequence in (r), except the unique ideal autocorrelation sequence in the family, is proved to have a large linear span n·2n/2-2, whilst the linear span of the latter is n · 2(n-2)/4-1.
