| NCMOS : Low Supply Current GCrystal Oscillator Modules GCommunication Equipment GMicrocomputers GClock Units in Motor Control GSystem Clocks on Boards GTimers GPalmtops NOscillator Frequency : 4MHz ~ 70MHz NBuilt-In Oscillator Capacitors NDivider Ratio N3-State Output NSupply Voltage : 5.0V NMini Mold SOT-26 Package : fo/1, fo/2, fo/4, fo/8 The XC2151 series are a group of high frequency, CMOS low power crystal oscillators with oscillator & divider circuitry, oscillator capacitors and amplifier feedback resistors built-in. An oscillator circuit can be created from just an external crystal. Output frequency can be selected from four frequencies : Fundamental f0/1, Divided f0/2, f0/4, f0/8. The output buffer is 3-State and has a fanout of 10 - TTL. High Precision : Built-in oscillator capacitors 16pF TYP (or selectable from 10 ~ 20pF) : On-chip amplifier feedback resistor 5M TYP (or selectable from 1.6k ~ 8.4k) Oscillator Frequency : 4MHz ~ 70MHz Divider Ratio : Selectable from f0/1, f0/2, f0/4, f0/8 Output : 3-State, 10 - TTL fanout Operating Voltage Range : 4.0V ~ 6.0V Small Quiescent Current Stand-By Function Low Cost : Oscillator circuit can be created from just an external crystal Ultra Small Package : SOT-26 (150mW) mini mold PIN NUMBER 1 2 3 4 5 6 PIN NAME /INH XT VSS Q0 V DD /XT FUNCTION Control * Oscillator Connection (Input) GND Output Power Supply Oscillator Connection (Output) * Control pin has pull-up resistor built-in.
