The device offers up to three configurable clock outputs in an 8-pin, 150-mil SOIC package and can operate off either a 3.3V or 5V power supply. The on-chip reference oscillator is designed for 10 MHz to 25 MHz crystals. Alternatively, an external reference clock of frequency between 1 MHz and 30 MHz can be used. 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. 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 Corporation web site at www.cypress.com. The CY2071A has one PLL and outputs three factory-EPROM configurable clocks: CLKA, CLKB, and CLKC. The output clocks can originate either from the PLL or the reference, or selected dividers thereof. Additionally, pin 8 can be configured to be an Output Enable or a Select input. Use the CY2081 for applications that require unrelated output frequencies. Use the CY2291, CY2292, or CY2907 for applications that require more than three output clocks. The CY2071A can replace multiple Metal Can Oscillators (MCO) in a synchronous system, providing cost and board space savings to the manufacturer. Hence, these devices are ideally suited for applications that require multiple, accurate, and stable clocks synthesized from low-cost generators in small packages. A hard-disk drive is an example of such an application. In this case, CLKA drives the PLL in the Read Controller, while CLKB and CLKC drive the MCU and associated sequencers. The Cypress Frequency Timing Generator (FTG) Programmer is a portable programmer designed to custom program our family of EPROM Field Programmable Clock Devices. The FTG programmers connect to a PC serial port and allow users of CyClocks software to easily program any of the CY2291F, CY2292F, CY2071AF, and CY2907F devices. The ordering code for the Cypress FTG Programmer is CY3670. Cypress FTG Programmer Absolute Maximum Conditions[3, 4] Parameter Description Condition Min.
