The CY22388 family of devices has an analog VCXO, four PLLs, up to eight clock outputs and frequency selection capabilities. The frequency selects do not modify any PLL frequency. Instead they allow the user to choose among eight different output divider selections depending on the clock and package configuration. This is illustrated in the Frequency Select Pin Operation tables and on page 1. To minimize parts per million (PPM) error on the clock outputs, you must choose a crystal reference frequency that is a common multiple of the desired PLL frequencies. While this is the ideal situation, this is not always the case and the PLLs have high-resolution counters internally to help minimize frequency deviation from the desired frequency. There is one programmable OE/PD#. The OE/PD# pin can be programmed as either an output enable pin or a power-down pin. The OE function can be programmed to disable a selected set of outputs when low, leaving the remaining outputs running. Full-chip power-down disables all outputs and the PLLs and most of the active circuitry when low. where FREF is the reference input frequency, P is the PLL feedback divider, and Q is the reference input divider. Factory-Programmable CY22388/89/91 Factory programming is available for high- or low-volume manufacturing by Cypress. All requests must be submitted to the local Cypress field application engineer (FAE) or sales representative. After the request is processed, you receive a new part number, samples, and datasheet with the programmed values. This part number is used for additional sample requests and production orders. PLL VCO frequencies are generated by the following equation: FVCO = FREF * (P / Q) A PLL is a feedback system where the VCO frequency divided by P and reference frequency divided by Q are constantly being compared and the VCO frequency is adjusted to achieve a locked state. Figure 4 is a simplified drawing of a PLL. Figure 4. PLL system F R E F /Q V C O a nd F V C O O th e r c o m p o n e n ts /P PLLs The advantage of having four PLLs is that a single device can generate up to four independent frequencies from a single crystal. Generally a design may require up to four oscillators to accomplish what could be done with a single CY22388. Frequency Select Pin Operation Each PLL is independent and can be configured to generate a voltage-controlled oscillator (VCO) frequency between 62.5 MHz and 250 MHz. Each PLL can then, in turn, be divided down with post dividers to generate the clock output frequency of the user’s choice. The output divider allows each clock output to be divided by 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 or 15. The PLL maximum is reduced to 166 MHz in ‘divide by 1’ mode due to output buffer limitations. CLK A Outputs that allow frequency switching perform a glitch-free transition. A glitch is defined as a high- or low-time shorter than half the smaller of the two periods being switched between. Extended low time (even many cycles in duration) is acceptable. Selected clock outputs are capable of being powered off a separate 2.5-V supply. This allows for driving lower voltage swing inputs. The CY22388/89/91 device still requires 3.3 V to power the oscillator and all other internal PLL circuitry. For the 2.5-V output option, refer to the CY22388 application note. Selected clocks and pinout diagrams are explained in this application note. Clock D can obtain its output from either the reference source or PLL1/N1 with N1 being defined as the output divider for PLL1. Clock H is defined as a copy of clock D. Clock D is only available from PLL1/N1 on the 16-pin package. For CY22388, CLKB and CLKC have related frequencies. For CY22389 and CY22391, CLKD and CLKF have related frequencies, CLKA and CLKB have related frequencies, and Document Number: 38-07734 Rev. *J Table 1.

The first mode uses an external pullable crystal and incorporates an internal analog VCXO. The second mode configures the internal crystal oscillator to accept an external driven reference source from 1 to 100 MHz. The input capacitance on the XIN PIN when driven in this mode is 15 pF. The third mode disables the VCXO input control and sets the internal oscillator to a fixed frequency operation. The load capacitance seen by the external crystal when connected to PINS XIN and XOUT is equal to 12 pF. One of the key components in the CY22388, CY22389, and CY22391 family of devices is the analog VCXO. The VCXO is used to ‘pull’ the reference crystal higher or lower to lock the system frequency to an external source. This is ideal for applications where the output frequency needs to track along with an external reference frequency that is constantly shifting. The VCXO is completely analog, so there is infinite resolution on the VCXO pull curve. The analog to digital converter steps that are normally associated with a digital VCXO input is not present in this device. A special pullable crystal must be used in order to have adequate VCXO pull range. Pullable crystal specifications are included in this datasheet. Document Number: 38-07734 Rev. *J Refer to the application note, Layout Recommendations for the CY22388, CY22389, and CY22391 Devices - ANC0001, for pullable crystal recommendations outside of the standard industry frequencies given in the Pullable Crystal specifications. VCXO Profile Figure 5 shows an example of what a VCXO profile looks like. The analog voltage input is on the X-axis and the PPM range is on the Y-axis. An increase in the VCXO input voltage results in a corresponding increase in the output frequency. This has the effect of moving the PPM from a negative to positive offset. Figure 5.
