Power Management
The individual output enable/freeze control of the CY29972
allows the user to implement unique power management
schemes into the design. The outputs are stopped in the logic ‘0’
state when the freeze control bits are activated. The serial input
register contains one programmable freeze enable bit for 12 of
the 14 output clocks. The QC0 and FB_OUT outputs can not be
frozen with the serial port, this avoids any potential lock up
situation should an error occur in the loading of the serial data.
An output is frozen when a logic ‘0’ is programmed and enabled
when a logic ‘1’ is written. The enabling and freezing of individual
outputs is done in such a manner as to eliminate the possibility
of partial “runt” clocks.
The serial input register is programmed through the SDATA input
by writing a logic ‘0’ start bit followed by 12 NRZ freeze enable
bits. The period of each SDATA bit equals the period of the free
running SCLK signal. The SDATA is sampled on the rising edge
of SCLK.
Absolute Maximum Ratings[5]
Maximum input voltage relative to VSS:.............. VSS – 0.3 V
Maximum input voltage relative to VDD:.............. VDD + 0.3 V
Storage temperature:................................ –65 °C to +150 °C
Operating temperature: .............................. –40 °C to +85 °C
Maximum ESD protection............................................... 2 kV
Maximum power supply:................................................ 5.5 V
Maximum input current: ............................................. ±20 mA
This device contains circuitry to protect the inputs against
damage due to high static voltages or electric field; however,
precautions should be taken to avoid application of any voltage
higher than the maximum rated voltages to this circuit. For proper
operation, VIN and VOUT should be constrained to the range:
VSS < (VIN or VOUT) < VDD .Unused inputs must always be tied
to an appropriate logic voltage level (either VSS or VDD).
Notes
3. For best performance and accurate frequencies from this device, It is recommended but not mandatory that the chosen crystal meet or exceed these specifications.
4. Larger values may cause this device to exhibit oscillator start-up problems.
5. Multiple Supplies: The voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
