CQ Lyn is a new double-lined spectroscopic binary, composed of an Am δ Scuti and a solar-like star, with an orbital period of 12.50736d and a zero-eccentricity. Physical parameters of both stars are well constrained. The characteristics of the primary are the following: M=1.714M_☉, T_eff=6760K, logL/L_☉=1.097 and logg=3.85dex. Power spectra of Hipparcos photometry and Coravel radial velocities show multi-period pulsation behaviour. Three frequencies are identified: f₁=8.86725, f₂=8.81150 and f₃=8.91007c/d and are assumed to be l=2 f-modes split by rotation, considering their pulsation constants Q₁=0.0356, Q₂=0.0359 and Q₃=0.0355d. Two combination oscillations are also present in the power spectrum at frequency f₁+f₂ and f₂+f₃.
