Functional Description
CY2077 is an EPROM-programmable, high-accuracy, general-purpose, PLL-based design for use in applications such as modems, disk drives, CD-ROM drives, video CD players, DVD players, games, set-top boxes, and data/telecommunications. CY2077 can generate a clock output up to 133 MHz at 5V or 100 MHz at 3.3V. It has been designed to give the customer a very accurate and stable clock frequency with little to zero PPM error. CY2077 contains a 12-bit feedback counter divider and 10-bit reference counter divider to obtain a very high resolution to meet the needs of stringent design specifications. Furthermore, there are eight output divide options of /1, /2, /4, /8, /16, /32, /64, and /128. The output divider can select between the PLL and crystal oscillator output/external clock, providing a total of 16 different options to add more flexibility in designs. TTL or CMOS duty cycles can be selected. Power management with the CY2077 is also very flexible. The user can choose either a PWR_DWN, or an OE feature with which both have integrated pull up resistors. PWR_DWN and OE signals can be programmed to have asynchronous and synchronous timing with respect to the output signal. There is a weak pull down on the output that pulls CLKOUT LOW when either the PWR_DWN or OE signal is active. This weak pull down can easily be overridden by another clock signal in designs where multiple clock signals share a signal path. Multiple options for output selection, better power distribution layout, and controlled rise and fall times enable the CY2077 to be used in applications that require low jitter and accurate reference frequencies.

PLL Output Frequency
CY2077 contains a high-resolution PLL with 12-bit multiplier and 10-bit divider.[2] The output frequency of the PLL is determined by the following formula: 2 * (P + 5) F PLL = --------------------------- * F REF (Q + 2) where P is the feedback counter value and Q is the reference counter value. P and Q are EPROM programmable values. The calculation of P and Q values for a given PLL output frequency is handled by the CyberClocksTM software. Refer to ""Programming Procedures" on page 12" for details.
Note 2. When using CyClocks, note that the PLL frequency range is from 50 MHz to 250 MHz for 5V VDD supply, and 50 MHz to 180 MHz for 3V VDD supply. The output frequency is determined by the selected output divider.

Power Management Features
PWR_DWN and OE options are configurable by EPROM programming for the CY2077. In PWR_DWN mode, all active circuits are powered down when the control pin is set LOW. When the control pin is set back HIGH, both the PLL and oscillator circuit must relock. In the case of OE, the output is three-stated and weakly pulled down when the control pin is set LOW. The oscillator and PLL are still active in this state, which leads to a quick clock output return when the control pin is set back HIGH. Table 3. Device Functionality: Output Frequencies Symbol Fo Description Output frequency Condition VDD = 4.5-5.5V VDD = 3.0-3.6V Min 0.39 0.39 Max 133 100 Unit MHz MHz Additionally, PWR_DWN and OE can be configured to occur asynchronously or synchronously with respect to CLKOUT. In asynchronous mode, PWR_DWN or OE disables CLKOUT immediately (allowing for logic delays), without respect to the current state of CLKOUT. Synchronous mode prevents output glitches by waiting for the next falling edge of CLKOUT after PWR_DWN, or OE becomes asserted. In either asynchronous or synchronous setting, the output is always enabled synchronously by waiting for the next falling edge of CLKOUT.

CY2077
Programming Procedures
Currently the CY2077 is available only as a field-programmable device, as indicated by an "F" in the ordering code. Devices may be programmed using the CY3670 programmer, or via programmers available from third party programmer manufacturers such as Hi-Lo Systems and BP Micro. Programming services are also available from third parties, including some Cypress distribution partners. To generate a JEDEC format programming file, customers should use CyClocks software. This software automatically calculates the output frequencies that can be generated by CY2077 devices. The CyClocks software is a subset of the larger software tool CyberClocks, which is available free of charge from the Cypress web site (http://www.cypress.com). CyberClocks is installed on a PC and should not be confused with the web-based application CyberClocks Online. For high volume designs, factory programming of customer-specific configurations is available on other 8-pin devices such as the CY22180, CY22801 and CY22381. Factory programming is no longer offered for new designs using the CY2077.
