CMOS PROGRAMMABLE FREQUENCY DIVIDER
KSS-EXO-3 Series
Features
· · · · · · · · · · · Frequency range 46.875kHz-20MHz Supply voltage range 3 to 6V Starting time <1.5mS Ultrasonic cleaning is available Suitable for various automatic assembly machines Low current consumption (CMOS IC structure) Standby function included High in noise margin Usable with no adjustment Most frequencies held ex-stock SMD version, see Seiko Epson
Dimensions (mm) Description
The KSS-EXO-3 is a super-small CMOS crystal clock oscillator in an 8-pin dip package equipped with a Programmable Frequency Divider. Division 1/2 to 1/28 simultaneously with the original frequency can be achieved at the user's freedom with this revolutionary device. Composed of an AT-cut oscillator and a specially designed CMOS IC divider, this device realises a wide range of supply voltage, lower power consumption, high speed operation and provides a standby function to meet most of the user's needs. This extraordinary device can utilise various pick & place machinery, replacing traditional oscillators.
Pin Connections
1.F Outputs the original frequency (fo) of the internal quartz crystal. 2.D Outputs the frequency of programmed dividing ratio (fo/2n). 3.ST Possible to be oscillated when set to HIGH level and stopped in oscillation when set to LOW level. When this function is not needed, be sure to set the STANDBY pin to the HIGH level. 4. Gnd 5.A, 6.B & 7.C Used to program the dividing ratio for the original frequency. 8.VDD

Handling Notes
Since this KSS-EXO type crystal clock oscillator employs a CMOS IC integrated with a protection circuit for static electricity, please handle only in an anti static environment. No by-pass capacitor is inserted between the power supply stage (VDD-Gnd). To protect from overvoltage and overcurrent due to power supply noise, provide a capacitor (above 0.01µF) as close as possible to the VDD-Gnd pin. If VDD is applied to Pin 4, a Gnd pin, mistaken as Pin 8 (VDD), ot an inverse current is applied to the device, it casuses an internal destruction or no oscillation in some cases. To avoid this, strict care should be taken over correct pin connection.
