MB88155
Spread Spectrum Clock Generator
Cypress Semiconductor Corporation 198 Champion Court San Jose,CA 95134-1709 408-943-2600
Document Number: 002-08298 Rev. *B Revised January 4, 2018
MB88155 is a clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary radiation noise (EMI) can
be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator. For modulation, the
MB88155 supports both center-spreading and down-spreading. It has a non-modulated clock output pin (REFOUT) as well as a
modulated clock output pin (CKOUT) .

5. Handling Devices
5.1 Preventing Latch-up
A latch-up can occur if, on this device, (a) a voltage higher than VDD or a voltage lower than VSS is applied to an input or output pin or
(b) a voltage higher than the rating is applied between VDD and VSS. The latch-up, if it occurs, significantly increases the power supply
current and may cause thermal destruction of an element. When you use this device, be very careful not to exceed the maximum rating.
5.2 Handling Unused Pins
Do not leave an unused input pin open, since it may cause a malfunction. Handle by, using a pull-up or pull-down resistor.
Unused output pin should be opened.
5.3 The Attention when the External Clock is Used
Input the clock to XIN pin, and XOUT pin should be opened when you use the external clock.
Please pay attention so that an overshoot and an undershoot do not occur to an input clock of XIN pin.
5.4 Power Supply Pins
Please design connecting the power supply pin of this device by as low impedance as possible from the current supply source.
We recommend connecting electrolytic capacitor (about 10 F) and the ceramic capacitor (about 0.01 F) in parallel between VSS
and VDD near the device, as a bypass capacitor.
5.5 Oscillation Circuit
Noise near the XIN and XOUT pins may cause the device to malfunction. Design printed circuit boards so that electric wiring of XIN
or XOUT pin and the resonator do not intersect other wiring.
Design the printed circuit board that surrounds the XIN and XOUT pins with ground.

7. Pin Setting
The modulation clock requires stabilization wait time after the PIN setting is changed. For the modulation clock stabilization wait time,
assure the maximum value for “Lock-up time” in the AC Characteristics list in “ Electrical Characteristics”.
ENS Modulation Enable Setting
Note : Spectrum does not diffuse when “L” is set to ENS pin.
MB88155-xx2, xx3 do not have ENS pin.
XPD Power Down
Note : When setting “L” to XPD pin, it becomes power down mode (low power consumption mode) .
Both CKOUT and REFOUT of output pins are fixed to “L” output during power down.
MB88155-xx0, xx1 do not have XPD pin.

16. Lock-Up Time
If the XPD pin is fixed at the “H” level, the maximum time after the power is turned on until the set clock signal is output from CKOUT
pin is (the stabilization wait time of input clock to XIN pin) (the lock-up time “tLK”). For the input clock stabilization time, check the
characteristics of the resonator or oscillator used.
If the XPD pin is used for power-down control, the set clock signal is output from the CKOUT pin at most the lock-up
time “tLK” after the XPD pin goes “H” level. (Continued)

(Continued)
If the ENS pin is used for modulation enable control during normal operation, the set clock signal is output from the CKOUT pin at
most the lock-up time “tLK” after the level at the ENS pin is determined.
Note : The wait time for the clock signal output from the CKOUT pin to become stable is required after the IC is released from power-
down mode by the XPD pin or after another pin’s setting is changed. During the period until the output clock signal becomes
stable, neither of the output frequency, output clock duty cycle, modulation period, and cycle-cycle jitter characteristic cannot
be guaranteed. It is therefore advisable to take action, such as cancelling a device reset at the stage after the lock-up time
has passed.

17. Oscillation Circuit
The following schematic on the left-hand side shows a sample connection of a general resonator. The oscillation circuit contains a
feedback resistor (1 M) . The values of capacitors (C1 and C2) must be adjusted to the optimum constant of the resonator used.
The following schematic on the right-hand side shows a sample connection of a 3rd overtone resonator. The values of capacitors (C1,
C2, and C3) and inductor (L1) must be adjusted to the optimum constant of the resonator used.
The most suitable value is different by individual resonator. Please refer to the resonator manufacturer which you use for the most
suitable value.
To use an external clock signal (without using the resonator) , input the clock signal to the XIN pin with the XOUT pin connected to
nothing.
