Models 636, 632, and 625 offer small package footprints while meeting similar electrical specifications of the larger 7mm x 5mm platform. Internal construction for Model 632 and Model 625 utilizes “flip chip” IC technology. These devices are ideal for applications where board space is a premium and excellent oscillator performance is still required. Low current consumption and “standby” enable/disable function make these devices ideally suited for portable product applications.
