_ XC2173 XC2173 SeriesICs for use with Crystal Oscillators (PLL built-in) General Description DETAILS Features The XC2173 XC2173 series are high frequency, low power consumption CMOS ICs with built-in crystal oscillator, divider and clock multiplier PLL circuits. Output is selectable from any one of the following values for f0 : f0 x 5, f0 x 6, f0 x 7 f0 x 8, f0/2, f0/4, , f0/8. With an oscillation capacitor & oscillation feedback resistor built-in, a stable oscillator circuit can be put together using only an external crystal oscillator. By connecting an external standard clock, the above mentioned output frequencies can be achieved. Pin Configuration Oscillation Frequency: 10MHz to 25MHz Divider Ratio: f0/2, f0/4, f0/8 Multiplier: f0 x 5, f0 x 6, f0 x 7 f0 x 8 , Output: 3 state Operating Voltage Range: 3.3V ± 10% and 5.0V ± 10% Small Consumption Current: Stand-by function included* * oscillation intermittent in stand-by Ultra Small Package: SOT-26 (150mW) mini mold Pin Assignment 1 /XT XT V DD VSS PIN NUMBER 1 2 3 4 5 QO SOT-26 ( TOP VIEW ) PIN NAME /INH XT VSS Qo VDD 6 /INH /XT FUNCTION Stand-by control* Crystal Oscillator Connection (Input) GND Clock Output Power Supply Crystal Oscillator Connection (Output) / Standard Clock Input * Stand-by control pin has pull-up resistance built-in.
