In this letter, the differential uniformity of power function f(x)=x^{e} over GF(3^{m}) is studied, where m≥3 is an odd integer and $e=rac{3^m-3}{4}$. It is shown that Δ_{f}≤3 and the power function is not CCZ-equivalent to the known ones. Moreover, we consider a family of ternary cyclic code C_{(1,e)}, which is generated by m_{ω}(x)m_{ωe}(x). Herein, ω is a primitive element of GF(3^{m}), m_{ω}(x) and m_{ωe}(x) are minimal polynomials of ω and ω^{e}, respectively. The parameters of this family of cyclic codes are determined. It turns out that C_{(1,e)} is optimal with respect to the Sphere Packing bound.
