• Manufacturer Part Number: DS1085
• Description: EconOscillator Frequency Synthesizer
• Manufacturer: Dallas Semiconductor

Table 2. DEVICE MODE USING OUT0
*This mode is for applications where OUT0 is not used, but CTRL0 is used as a device shutdown.
**Factory default setting.
***See standby (power-down) current specification for power-down current range.
Table 3. DEVICE MODE USING OUT1
*Factory default setting.
NOTE:
Both CTRL0 and CTRL1 can be configured as power-downs. They are internally “OR” connected so
either of the control pins can be used to provide a power-down function for the whole device, subject to
appropriate settings of the PDN0 and PDN1 register bits (see Table 4).
