Laser trimming gives the option of being able to select from divider ratios (M) of 1 to 2047 and multiplier ratio (N) of 20 to 2047. Output frequency (Q0) is equal to reference oscillation (fCLKin) multiplied by N/M, within a range of 9MHz to 80MHz. Q1 output is selectable from input reference frequency (f0), Ground (GND), PLL output frequency/2 (Q0/2), and comparative frequency/2 (f0/M/2). Reference oscillation can input 14kHz to 35MHz of reference clock. Further, comparative frequency, within a range of 14kHz to 500kHz, can be obtained by dividing the reference oscillation. By halting oscillation via the CE pin, consumption current can be controlled. Output will be one of high impedance. ■ APPLICATIONS ● Crystal oscillation modules ● Microcontroller ● PDAs ● Portable audio systems ● Various system clocks ■ PIN CONFIGURATION ■ FEATURES Output Frequency : 9MHz ~ 80MHz (Q0=fCLKin×N/M) Reference Oscillation : 14kHz ~ 35MHz (fCLKin) Divider Ratio (M) : Selectable from divisions of 1 ~ 2047 Multiplier Ratio (N) : Selectable from multiplications of 20 ~ 2047 Output : 3-State Q1 output selectable from reference oscillation, GND, PLL output frequency/2, comparative frequency/2. Operating Voltage Range: 2.97V ~ 5.5V Low Power Consumption: CMOS (stand-by function included)*1 Ultra Small Package : SOT-26, USP-6B *1 High output impedance during stand-by ■ PIN ASSIGNMENT *The dissipation pad for the USP-6B package should be solder-plated in recommended mount pattern and metal masking so as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VDD pin. Q1 VDD CLKin Q0 VSS CE SOT-26 (TOP VIEW) * Q1 Output is selectable from the above mentioned functions. |
