CDCE62005 Device State Definitions STATUS STATE DEVICE BEHAVIOR ENTERED VIA EXITED VIA OUTPUT OUTPUT SPI PORT PLL DIVIDER BUFFER After device power supply reaches Power applied to the device or upon exit Power On Reset and EEPROM loading delays OFF Disabled Disabled OFF approximately 2.35 V, the contents of from Power Down State via the are finished OR the Power_Down pin is set Power-On EEPROM are copied into the Device Power_Down pin set HIGH. LOW. Reset Registers within 100ns, thereby initializing the device hardware. The device waits until either Delay process in the Power-On Reset The device waits until either ENCAL_MODE ON Enabled Disabled OFF ENCAL_MODE (Device Register 6 bit State is finished or Sleep Mode (Sleep bit (Device Register 6 bit 27) is low (Start up 27) is low (Start up calibration enabled) is in Register 8 bit 7) is turned OFF while calibration enabled) or both ENCAL_MODE is Calibration or both ENCAL_MODE is high (Manual in the Sleep State. Power Down must be high (Manual Calibration Enabled) AND ENCAL Hold Calibration Enabled) AND ENCAL OFF to enter the Calibration Hold State. (Device Register 6 bit 22) transitions from a low (Device Register 6 bit 22) transitions to a high signaling the device from a low to a high signaling the device. Calibration Hold: CAL Enabled becomes Calibration Process in completed ON Enabled Disabled OFF true when either ENCAL_MODE (Device Register 6 bit 27) is low or both ENCAL_MODE is high AND ENCAL The voltage controlled oscillator is (Device Register 6 bit 22) transitions from calibrated based on the PLL settings a low to a high. VCO CAL and the incoming reference clock. After Active Mode: A Manual Recalibration is the VCO has been calibrated, the device requested. This is initiated by setting enters Active Mode automatically. ENCAL_MODE to HIGH (Manual Calibration Enabled) AND initiating a calibration sequence by applying a LOW to HIGH transition on ENCAL. CAL Done (VCO calibration process Sync, Power Down, Sleep, or Manual ON Enabled Disabled or Enabled HI-Z or Enabled Active Mode Normal Operation finished) or Sync = OFF (from Sync State). Recalibration activated. Used to shut down all hardware and Power_Down pin is pulled LOW. Power_Down pin is pulled HIGH. OFF Disabled Disabled HI-Z Resets the device after exiting the Power Down State. Therefore, the Power Down EEPROM contents will eventually be copied into RAM after the Power Down State is exited. Identical to the Power Down State Sleep bit in device register 8 bit 7 is set Sleep bit in device register 8 bit 7 is set HIGH. ON Disabled Disabled HI-Z Sleep except the EEPROM contents are not LOW. copied into RAM. Sync synchronizes all output dividers so Sync Bit in device register 8 bit 8 is set Sync Bit in device register 8 bit 8 is set HIGH or ON Enabled Disabled HI-Z that they begin counting at the same LOW or Sync pin is pulled LOW Sync pin is pulled HIGH Sync time. Note: this operation is performed automatically each time a divider register is accessed. 22 Submit Documentation Feedback Copyright © 2008–2015, Texas Instruments Incorporated Product Folder Links: CDCE62005 |
