an external differential ECL/PECL feedback to the PLL. This external feedback feature allows for the MPC991’s use as a “zero” delay buffer. The propagation delay between the input reference and the output is dependent on the input reference frequency. The selection of higher reference frequencies will provide near zero delay through the device. The PLL_En, Ref_Sel and the Test_Clk input pins provide a means of bypassing the PLL and driving the output buffers directly. This allows the user to sin.
