9 / 23 page www.ti.com APPLICATION INFORMATION CONTROL TERMINAL CONFIGURATION CDCE913 CDCEL913 SCAS849A – JUNE 2007 – REVISED AUGUST 2007 The CDCE913/CDCEL913 has three user-definable control terminals (S0, S1, and S2) which allow external control of device settings. They can be programmed to any of the following functions: • Spread spectrum clocking selection → spread type and spread amount selection • Frequency selection → switching between any of two user-defined frequencies • Output state selection → output configuration and power down control The user can predefine up to eight different control settings. Table 1 and Table 2 explain these settings. Table 1.
