The CY22392 is an upgrade to the existing CY2292. The new device has a wider frequency range, greater flexibility, improved performance, and incorporates many features that reduce PLL sensitivity to external system issues. The value of the load capacitors is determined by six bits in a programmable register. The load capacitance can be set with a resolution of 0.375 pF for a total crystal load range of 6 pF to 30 pF. The device has three PLLs which, when combined with the reference, enable up to four independent frequencies to be output on up to six pins. These three PLLs are completely programmable. For driven clock inputs the input load capacitors may be completely bypassed. This enables the clock chip to accept driven frequency inputs up to 166 MHz. If the application requires a driven input, then XTALOUT must be left floating. Configurable PLLs PLL1 generates a frequency that is equal to the reference divided by an 8-bit divider (Q) and multiplied by an 11-bit divider in the PLL feedback loop (P). The output of PLL1 is sent to the crosspoint switch. The output of PLL1 is also sent to a /2, /3, or /4 synchronous post-divider that is output through CLKE. The frequency of PLL1 can be changed by external CMOS inputs, S0, S1, S2. See the following section on General Purpose Inputs for more details. PLL2 generates a frequency that is equal to the reference divided by an 8-bit divider (Q) and multiplied by an 11-bit divider in the PLL feedback loop (P). The output of PLL2 is sent to the crosspoint switch. PLL3 generates a frequency that is equal to the reference divided by an 8-bit divider (Q) and multiplied by an 11-bit divider in the PLL feedback loop (P). The output of PLL3 is sent to the cross-point switch. General Purpose Inputs S0, S1, and S2 are general purpose inputs that can be programmed to enable eight different frequency settings. Options that may be switched with these general purpose inputs are as follows: the frequency of PLL1, the output divider of CLKB, and the output divider of CLKA. CLKA and CLKB both have 7-bit dividers that point to one of two programmable settings (register 0 and register 1). Both clocks share a single register control, so both must be set to register 0, or both must be set to register 1. For example, the part may be programmed to use S0, S1, and S2 (0, 0, 0 to 1, 1, 1) to control eight different values of P and Q on PLL1. For each PLL1 P and Q setting, one of the two CLKA and CLKB divider registers can be chosen. Any divider change as a result of switching S0, S1, or S2 is guaranteed to be glitch free. Crystal Input The input crystal oscillator is an important feature of this device because of its flexibility and performance features. The oscillator inverter has programmable drive strength. This enables maximum compatibility with crystals from various manufacturers, processes, performances, and qualities. The input load capacitors are placed on-die to reduce external component cost. These capacitors are true parallel-plate capacitors for ultra-linear performance. These were chosen to reduce the frequency shift that occurs when non-linear load capacitance interacts with load, bias, supply, and temperature changes. Non-linear (FET gate) crystal load capacitors must not be used for MPEG, POTS dial tone, communications, or other Document Number: 38-07013 Rev. *K are sensitive to absolute frequency Output Configuration Under normal operation there are four internal frequency sources that may be routed through a programmable crosspoint switch to any of the four programmable 7-bit output dividers. The four sources are: reference, PLL1, PLL2, and PLL3. In addition, many outputs have a unique capability for even greater flexibility. The following is a description of each output. CLKA’s output originates from the crosspoint switch and goes through a programmable 7-bit post divider. The 7-bit post divider derives its value from one of two programmable registers. Each of the eight possible combinations of S0, S1, S2 controls which of the two programmable registers is loaded into CLKA’s 7-bit post divider. See the section General Purpose Inputs for more information. CLKB’s output originates from the crosspoint switch and goes through a programmable 7-bit post divider. The 7-bit post divider derives its value from one of two programmable registers. Each of the eight possible combinations of S0, S1, and S2 controls which of the two programmable registers is loaded into CLKA’s 7-bit post divider. See the section General Purpose Inputs for more information. CLKC’s output originates from the crosspoint switch and goes through a programmable 7-bit post divider. The 7-bit post divider derives its value from one programmable register. CLKD’s output originates from the crosspoint switch and goes through a programmable 7-bit post divider. The 7-bit post divider derives its value from one programmable register. CLKE’s output originates from PLL1 and goes through a post divider that may be programmed to /2, /3, or /4. XBUF is simply the buffered reference. The clock outputs have been designed to drive a single point load with a total lumped load capacitance of 15 pF. While driving multiple loads is possible with proper termination, it is generally not recommended. Power Saving Features The SHUTDOWN/OE input tristates the outputs when pulled low. If system shutdown is enabled, a Low on this pin also shuts off the PLLs, counters, the reference oscillator, and all other active components. The resulting current on the VDD pins is less than 5 A (typical). After leaving shutdown mode, the PLLs must relock. The S2/SUSPEND input can be configured to shut down a customizable set of outputs and/or PLLs, when LOW. All PLLs and any of the outputs can be shut off in nearly any combination. The only limitation is that if a PLL is shut off, all outputs derived from it must also be shut off. Suspending a PLL shuts off all Page 4 of 14 CY22392 Jitter Optimization Control is useful in mitigating problems related to similar clocks switching at the same moment, causing excess jitter. If one PLL is driving more than one output, the negative phase of the PLL can be selected for one of the outputs (CLKA–CLKD). This prevents the output edges from aligning, enabling superior jitter performance. unprogrammed, and must be programmed prior to installation on a PCB. After a programming file (.jed) is created using CyberClocks software, devices can be programmed in small quantities using the CY3672 programmer and CY3698 [1] adapter. Volume programming is available through Cypress Semiconductor’s value added distribution partners or by using third party programmers from BP Microsystems, HiLo Systems, and others. For sufficiently large volumes, Cypress can supply pre-programmed devices with a part number extension that is configuration-specific. Power Supply Sequencing Junction Temperature Limitations For parts with multiple VDD pins, there are no power supply sequencing requirements. The part is not fully operational until all VDD pins have been brought up to the voltages specified in the Operating Conditions. All grounds must be connected to the same ground plane. It is possible to program the CY22392 such that the maximum junction temperature rating is exceeded. The package JA is 115 C/W. Use the CyClocksRT power estimation feature to verify that the programmed configuration meets the junction temperature and package power dissipation maximum ratings. CyberClocks™ Software Maximum Ratings The CyberClocks application enables users to configure this device. Within CyberClocks, select the CyClocksRT tool. The easy-to-use interface offers complete control of the many features of this family including input frequency, PLL, output frequencies, and different functional options. Data sheet frequency range limitations are checked and performance tuning is automatically applied. CyClocksRT also has a power estimation feature that enables you to see the power consumption of your specific configuration. Download a copy of CyberClocks free on Cypress’s web site at www.cypress.com. Install and run it on any PC running Windows. Exceeding maximum ratings may shorten the useful life of the device.
