The advantage of having two PLLs is that a single device generates two independent frequencies from a single crystal. When the frequency select pin, FS(1:0) is used to switch frequency, the outputs are glitch-free provided frequency is switched using output dividers. This feature enables uninterrupted system operation while clock frequency is being switched. Input Reference Clocks PD#/OE Mode The input reference clock can be either a crystal or a clock signal, for CY25402 and CY25422 while just a clock signal for CY25482. The input frequency range for crystal (XIN) is 8 MHz to 48 MHz and that for external reference clock (EXCLKIN) is 8 MHz to 166 MHz. The voltage range of the reference clock input for CY25482 is 2.5 V/3.0 V/3.3 V while that for CY25402 and CY25422 is 1.8 V. This gives user an option for this device to be compatible for different input clock voltage levels in the system. Multifunction pin PD#/OE/FS1 (Pin 5) can be programmed to operate as either frequency select (FS1), power down (PD#) or output enable (OE) mode. PD# is a low-true input. If activated it shuts off the entire chip, resulting in minimum power consumption for the device. Setting this signal high brings the device in the operational mode with default register settings. VDD Power Supply Options When this pin is programmed as Output Enable (OE), clock outputs can be enabled or disabled using OE (pin 5). Individual clock outputs can be programmed to be sensitive to this OE pin. These devices have programmable power supply options. The CY25402/CY25482 is a high voltage part that can be programmed to operate at any voltage 2.5 V, 3.0 V, or 3.3 V while CY25422 is a low voltage part that can operate at 1.8 V. Output Drive Strength Output Source Selection Table 5. Output Drive Strength These devices have programmable input sources for each of its clock outputs. There are three available clock sources and these clock sources are: XIN/EXCLKIN, PLL1, and PLL2. Output clock source selection is done by using three out of three crossbar switch. Thus, any one of these three available clock sources can be arbitrarily selected for the clock outputs. This gives user a flexibility to have two independent clock outputs. The DC drive strength of the individual clock output can be programmed for different values. Table 4 on page 4 shows the typical rise and fall times for different drive strength settings. Output Drive Strength Rise/Fall Time (ns) (Typical Value) Low 6.8 Mid Low 3.4 Mid High 2.0 High 1.0 Spread Spectrum Control Both PLLs (PLL1 and PLL2) have spread spectrum capability for EMI reduction in the system. The device uses a Cypress proprietary PLL and spread spectrum clock (SSC) technology to synthesize and modulate the frequency of the PLL. The spread spectrum feature can be turned on or off using a multifunction control pin (CLK2/SSON). It can be programmed to either center spread range from 0.125% to 2.50% or down spread range from -0.25% to -5.0% with lexmark or linear profile. Generic Configuration and Custom Frequency There is a generic set of output frequencies available from the factory that can be used for the device evaluation purposes. The devices, CY25402, CY25422, and CY25482 can be custom programmed to any desired frequencies and listed features. For customer specific programming, please contact local Cypress field application engineer (FAE) or sales representative. Frequency Select Each PLL can be programmed for up to four different frequencies. There are two multifunction programmable pins, REFOUT/FS0 and PD#/OE/FS1 which if programmed as frequency select inputs, can be used to select among these arbitrarily programmed frequency settings. Each output has programmable output divider options.
