CQ Lyn is a new double-lined spectroscopic binary, composed of an Am delta Scuti and a solar-like star, with an orbital period of 12.50736 d and a zero-eccentricity. Physical parameters of both stars are well constrained. The characteristics of the primary are the following: M = 1.714 M., T-eff = 6760 K, log L/L. = 1.097 and log g = 3.85 dex. Power spectra of Hipparcos photometry and Coravel radial velocities show multi-period pulsation behaviour. Three frequencies are identified. f(1) = 8.86725, f(2) = 8.81150 and f(3) = 8.91007 c/d and are assumed to be l = 2 f-modes split by rotation, considering their pulsation constants Q(1) = 0.0356, Q(2) = 0.0359 and Q(3) = 0.0355 d. Two combination oscillations are also present in the power spectrum at frequency f(1)+f(2) and f(2)+f(3).
