The low jitter and accurate outputs makes this device suitable for handsets, portable media players, personal navigation devices, digital cameras, digital camcorders, and other portable applications. The MoBL® UniClock CY22M1 offers PD# (active LOW) and OE (active HIGH) functions. When the power down mode is selected (PD# =0), the oscillator and PLL are placed in a low supply current standby mode and the output is tristated and weakly pulled LOW. The oscillator and PLL circuits must relock when the part exits the power down mode. If the output is disabled (OE=0), the output is tristated and weakly pulled LOW. In this mode, the oscillator and PLL circuits continue to operate, which enables a rapid return to normal operation when the output is enabled. The device has several programmable options listed in the section Programmable Features on page 4 of this data sheet. The entire configuration is one time programmable. Configurable PLL The device uses a programmable PLL to generate output frequencies from 1 to 80 MHz. The high resolution of the PLL and flexible output dividers provide this flexibility. Input Reference Clock Option There is an option of a crystal or clock signal for the input reference clock. The frequency range for crystal (XIN) is 8 MHz to 48 MHz, while the range for an external reference clock (CLKIN) is 1 MHz to 80 MHz. A PLL bypass mode enables this device to be used as a crystal oscillator. Multiple VDD Power Supply Option The device has programmable power supply options. The operating supply voltages are 2.5V, 3.0V, or 3.3V for CY22M1S and 1.8V for CY22M1L. Programmable Output Drive Strength The DC drive strength of the clock output can be programmed to one of two settings, enabling control of output rise and fall times. Table 2 shows the typical rise and fall times for both of the drive strength settings. Table 2. Output Drive Strength Output Drive Strength In addition, the PD# or OE mode can be programmed to occur asynchronously or synchronously with respect to the output signal. When the asynchronous setting is used, entering power down or disabling the output occurs immediately (enabling logic delays) regardless of the position in the clock cycle. Similarly, exiting power down or enabling the output occurs immediately with no guarantee of full output clock pulses. However, when the synchronous setting is used, the part waits for a falling edge at the output before entering power down or disabling the output. This prevents output glitches. The first output pulse is guaranteed to be a full clock pulse when enabling outputs with a synchronous OE pin. The first output pulse is not guaranteed to be a full clock when exiting power down in synchronous or asynchronous mode. Output Frequency Tuning The MoBL® UniClock CY22M1 contains an on-chip oscillator with a built-in programmable capacitor array for fine tuning of the output frequency. The capacitive load seen by the crystal is adjusted by programming the memory bits. This feature can compensate for crystal variations or provide a more accurate synthesized frequency. Figure 2 on page 4 shows the crystal oscillator tuning circuit block diagram.
