Description Frequency Select (CLKA) (Internal pull-up resistor to VDD) Frequency Select (CLKA) (Internal pull-up resistor to VDD) Frequency Select (CLKA) (Internal pull-up resistor to VDD) Ground Power-Down (active LOW) (Internal pull-up resistor to VDD) Reference Crystal Input Reference Crystal Feedback REFCLK Output Enable (active HIGH) (Internal pull-up resistor to VDD) CLKA Output Enable (active HIGH) (Internal pull-up resistor to VDD) Clock Output Voltage Supply Reference Clock Output (Default, can be driven by PLL if desired) Frequency Select (CLKA) (Internal pull-up resistor to VDD)

Notes: 1. For best accuracy, use a parallel-resonant crystal, CLOAD 17 pF. 2. Float XTALOUT pin if XTALIN is driven by reference clock (as opposed to crystal).

The is a general-purpose Clock Generator designed for use in a wide variety of applications--from graphics to PC peripherals to disk drives. It generates selectable system clock frequencies from a single reference input (crystal or reference clock). The CY2907 is configured with an EPROM array, much like the other devices in the Cypress EPROM Programmable Clock Family, making it easily customizable for any application. Furthermore, the CY2907 is compatible with all industry-standard 9107 and 9108 clock synthesizers.

The Cypress Frequency Timing Generator (FTG) Programmers are portable programmers designed to custom program our family of EPROM Field Programmable Clock Devices. The FTG programmers connect a PC serial port and allow users of CyClocks software to quickly and easily program any of the CY2292F, CY2071AF, and CY2907F devices. The ordering code for the Cypress FTG Programmer is CY3670.

CyClocks is an easy-to-use software application that allows you to configure any one of the EPROM Programmable Clocks offered by Cypress. You may specify the input frequency, PLL and output frequencies, and different functional options. Please note the output frequency ranges in this data sheet when specifying them in CyClocks to ensure that you stay within the limits. You can download a copy of CyClocks free on the Cypress Semiconductor website at Consider using the or CY2292 for applications that require unrelated and multiple output frequencies. Consider using the CY2071A for applications that require more than one output clock.

Notes: 3. Electrical parameters are guaranteed with these operating conditions. 4. Guaranteed by design, not 100% tested in production. 5. Load = max. typical configuration, fREF = 14.318 MHz. Specific configurations may vary. A close approximation of IDD can be derived by the following formula: IDD (mA) = VDD (0.0017*CLOAD*(FCLKA + REFCLK))). CLOAD is specified in pF and F is specified in MHz.
