cy2077 document number: 38-07210 rev. *g page 3 of 17 pinouts figure 1. pin diagram - 8 pin top view 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 5 v or 100 mhz at 3.3 v. 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 s pecifications. 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 low. 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. eprom configuration block table 2. eprom adjustable features pll output frequency cy2077 contains a high-resolutio n pll with 12-bit multiplier and 10-bit divider. [2] the output frequency of the pll is determined by the following formula: 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 cyberclocks ? software. refer to ? ?programming procedures? on page 13? for details. 1 2 3 4 5 8 7 6 v dd xtalout xtalin pd/oe v ss clkout v ss v ss table 1. pin definition - 8 pin pin name pin # pin description v dd 1 voltage supply v ss 5,6,7 ground (all the pins must be grounded) x d 2 crystal output (leave this pin floating when external reference is used) x g 3 crystal input or external input reference pwr_dwn / oe 4 eprom programmable power down or output enable pin. pwr_dwn is active low. oe is active high. weak pull up. clkout 8 clock output. weak pull down eprom adjustable features adjust freq. feedback counter value (p) reference counter value (q) output divider selection duty cycle levels (ttl or cmos) power management mode (oe or pwr_dwn) power management timing (synch ronous or asynchronous) f pll 2p5 + ?? ? q2 + ?? --------------------------- f ref ? = note 2. when using cyclocks, note that the pll frequency range is from 50 mhz to 250 mhz for 5 v v dd supply, and 50 mhz to 180 mhz for 3 v v dd supply. the output frequency is determined by the selected output divider.
cy2077 document number: 38-07210 rev. *g page 4 of 17 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. 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 asse rted. in either asynchronous or synchronous setting, the output is always enabled synchronously by waiting for the next falling edge of clkout. absolute maximum ratings exceeding maximum ratings may s horten the useful life of the device. user guidelines are not tested. supply voltage ........................... ...................... ?0.5 to +7.0 v input voltage ......................................... ?0.5 v to v dd +0.5 v storage temperature (non-condensing)...... ?55c to +150c junction temperature.................................................. 150c static discharge voltage.......................................... > 2000 v (per mil-std-883, method 3015) operating conditions for co mmercial temperature device table 3. device functionality: output frequencies symbol description condition min max unit fo output frequency v dd = 4.5?5.5 v 0.39 133 mhz v dd = 3.0?3.6 v 0.39 100 mhz parameter description min max unit v dd supply voltage 3.0 5.5 v t a operating temperat ure, ambient 0 +70 c c ttl max. capacitive load on outputs for ttl levels v dd = 4.5 ? 5.5 v, output frequency = 1 ? 40 mhz v dd = 4.5 ? 5.5 v, output frequency = 40 ? 125 mhz v dd = 4.5 ? 5.5 v, output frequency = 125 ? 133 mhz ? ? ? 50 25 15 pf pf pf c cmos max. capacitive load on outputs for cmos levels v dd = 4.5 ? 5.5 v, output frequency = 1 ? 40 mhz v dd = 4.5 ? 5.5 v, output frequency = 40 ? 125 mhz v dd = 4.5 ? 5.5 v, output frequency = 125 ? 133 mhz v dd = 3.0 ? 3.6 v, output frequency = 1 ? 40 mhz v dd = 3.0 ? 3.6 v, output frequency = 40 ? 100 mhz ? ? ? ? ? 50 25 15 30 15 pf pf pf pf pf x ref reference frequency, input crystal with c load = 10 pf 10 30 mhz reference frequency, external clock source 1 75 mhz t pu power up time for all vdd's to reach minimum specified voltage (power ramps must be monotonic) 0.05 50 ms
