... Freescale Semiconductor, Inc. Pin Connections 3 Pin Connections 3.1 Digital Interface Pins D in Serial Data Input (Pin 5) The bit stream begins with the most significant bit (MSB) and is shifted in on the low-to-high transition of CLK. The bit pattern is 1 byte (8 bits) long to access the C or configuration register, 2 bytes (16 bits) to access the N register bytes (24 bits) to access the R register ...

... Freescale Semiconductor, Inc. ENB Active-Low Enable Input (Pin 6) This pin is used to activate the serial interface to allow the transfer of data to/from the device. When ENB inactive high state, shifting is inhibited, D held in the initialized state. To transfer data to the device, ENB (which must start inactive high) is taken low, a serial transfer is made via Din and CLK, and ENB is taken back high ...

Pin Connections REF out Reference Frequency Output (Pin 3) This output is the buffered output of the crystal-generated reference frequency or externally provided reference source. This output may be enabled, disabled, or scaled via bits in the C register (see Figure 16). REF can be used to drive a microprocessor clock input, thereby saving a crystal. Upon power up, the on- ...

... Freescale Semiconductor, Inc. For signals which swing from at least the V dc coupling may be used. Also, for low frequency signals (less than the minimum frequencies shown in the Loop Specifications table), dc coupling is a requirement. The N counter is a static counter and may be operated down to dc. However, wave shaping by a CMOS buffer may be required to ensure fast rise and fall times into the f pin ...

... Freescale Semiconductor, Inc. To verify that the maximum dc supply voltage does not cause the crystal to be overdriven, monitor the output frequency at the REF pin (OSC out frequency should increase very slightly as the dc supply voltage is increased. An overdriven crystal decreases in frequency or becomes unstable with an increase in supply voltage. The operating supply voltage must be reduced or R1 must be increased in value if the overdriven condition exists ...
