The XC25BS6 is a low operating voltage, low current consumption series of CMOS ICs with built-in crystal oscillator and divider circuits designed for clock generators. Oscillation capacitors Cg and Cd are externally set up. Output is selectable from any one of the following values for f0:f0/1024, f0/512, f0/256, and f0/128. With oscillation feedback resistors built-in, it is possible to configure a stable fundamental oscillator using about 10pF of external oscillation capacitor and an external crystal. The series has a stand-by function. The oscillation completely stops in the stand-by state and output will be one of high-impedance. 1/XT VSS XT VDD CE VDD CEXT /XT VSS VSS(NC) VDD (1300,800) (0,0) Chip Size Chip Thickness Chip Back Pad Aperture : 1300 x 800µm : 280±20µm : VDD level : 88 x 88 µm Note) There are two VSS pads and two VDD pads.

Divider Signal Output Clock Generator ICs with Built-In Crystal Oscillator Circuit Preliminary WIRE BONDING CONNECTION TYPICAL APPLICATION CIRCUIT * Please use oscillation capacitors Cg, Cd =10pF externally * The same power supply can be used for VDD and CE. NOTES ON USE (1) The oscillation circuit of this IC does not have internal oscillation capacitors. Please make the oscillation circuitry using an external crystal transducer and oscillation capacitors Cg and Cd. *) A higher harmonic wave oscillation may occur without Cg and Cd. *) Cg and Cd can be connected either to GND or VDD. (Cg and Cd in the above circuit example are connected to GND.) *) It is recommended to use around for 10pF of Cg and Cd. For trimmer capacitors, 10pF as a standard value is appropriate. *) The crystal oscillation frequency should be measured at the output of the Q0 pin. When a probe is directly connected to the XT pin or the /XT pin, oscillation frequency will change and a precise value can not be taken. (2) Please insert a by-pass capacitor of 0.1µF between VDD and GND. (3) The use of a matching resistor Rq0 of 50Ω connected in series to the Q0 pin is recommended in order to counter unwanted radiations. (5) When the CE pin is not controlled by external signals, please connect the CE pin to VDD power supply. *) When the CE pin is not connected, the IC goes into stand-by mode due to the internal pull-down resistor. (6) As for the supply voltage, it is recommended to apply a low noise power supply, such as a series regulator. Using a power supply like a switching regulator might lead to an unstable oscillation jitter which in turn may lead the oscillation frequency to fluctuate due to the ripple of the switching regulator. (4) Please place a by-pass capacitor and the matching resistor as close to the IC as possible. If the by-pass capacitor is placed away from the IC, it may cause abnormal oscillation. If the matching resistor is placed away from the IC, it may cause unwanted radiations in the pattern between the Q0 pin and the resistor. * There are two VSS pads and VDD pads. Please connect both VSS pads to GND, and connect both VDD pads to a power supply. Semiconductor Ltd. VDD CEXT /XT VSS VSS VDD (NC) fQ0 measurement VDD /XT XT VSS CE CgCd Rq0 0.1uF Data Sheet 3
