SMD Low ESR Crystal ABS06-107-32.768kHz-T Pb RoHS/RoHS II Compliant 2.0 x 1.2 x 0.6mm ||||||| | | | | | | | | Moisture Sensitivity Level (MSL) – This product is Hermetically Sealed and not Moisture Sensitive - MSL = N/A: Not Applicable FEATURES: APPLICATIONS: • Wide range in communication & measuring equipment • 0.6mm max. height ideal for high density circuit boards • Commercial & Industrial applications • Ceramic package offers excellent environmental & heat resistance • Wireless communications • Extended temperature -40°C to +85°C for industrial applications Overview ABRACON’s ABS06-107-32.768kHz-T Tuning Fork Crystal is optimized for Power Sensitive Designs, requiring minimal plating load (4pF) and Ultra-Low ESR. With guaranteed maximum ESR of 80kΩ, this device is ideally suited for Ultra-Low Power - Real Time Clocking solutions, requiring exceptionally low power consumption (Reference; ST Micro STM32L1, F2 & F4 µcontrollers). Key Attributes • 4pF plating load facilitates sustained oscillations with very low oscillator loop transconductance (g ) < 3µA/V m • Guaranteed maximum ESR of 80kΩ ensures lower overall power consumption & higher Gain Margin • Tight Frequency Set Tolerance < ±20 ppm into a 4pF Effective Oscillator Loop Load • Wide Operating Temperature Range (-40ºC to +85ºC) • < ±175 ppm typical stability over -40ºC to +85ºC; ±250 ppm guaranteed; referenced to measured frequency at 25ºC±3ºC • Developed in close-cooperation with ST Micro for STM32L1, F2 & F4 Reference Designs • Space saving 2.0x1.2x0.6 mm, RoHS Compliant SMT package • Low cost, available through Abracon’s Global Distributors Reference Design Information ABS06-107-32.768kHz-T device is Qualified on the following ST Micro’s Reference Designs: STM32F2 Series: http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1575 STM32F4 Series: http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1577 STM32L1 Series: http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1295 Visit www.abracon.com for Terms & Conditions of Sale Revised: 07.11.13 ABRACON IS ABRACON IS ISO 9001 / QS 9000 ISO 9001:2008 30332 Esperanza, Rancho Santa Margarita, California 92688 CE CER RTIFIED TIFIED tel 949-546-8000 | fax 949-546-8001| www.abracon.com SMD Low ESR Crystal ABS06-107-32.768kHz-T Pb RoHS/RoHS II Compliant 2.0 x 1.2 x 0.6mm ||||||| | | | | | | | | STANDARD SPECIFICATIONS: Parameters Minimum Typical Maximum Units otes Frequency 32.768 kHz Operation Mode Flexural Mode (Tuning Fork) Operating Temperature -40 +85 ºC Storage Temperature -55 +125 ºC Temperature Coefficient: -0.039 -0.034 -0.029 ppm/T² Turn-over temperature: +20 +25 +30 ºC Relative to the Frequency Stability over temperature -250 < ±175 +250 ppm measured frequency at 25ºC ± 3ºC Equivalent series resistance (R1) < 60 80 kΩ Shunt Capacitance (C0) < 1.50 1.70 pF Load capacitance (CL) 3.90 4.00 4.10 pF See Note#1 See Note#2 Frequency Tolerance @+25°C -20 +20 ppm Tested at 0.5µW Drive Level 0.1 0.5 µW Q value 9000 20,000 Aging@25°C±3°C -3 3 ppm First year Insulation Resistance 500 MΩ @ 100Vdc ± 15V Note #1: The oscillator loop needs to present an effective loop capacitance of 4.0 pF, not to exceed 4.50 pF. This loop capacitance is required to ensure Safety Factor of > 5.0 for the entire population of crystals. Note #2: With an effective loop capacitance of 4.0 pF, the oscillator circuit will be with-in (32.768 kHz) ±20 ppm. Depending on production equipment capability, these parts might be tested at a different load, with guaranteed projected performance at 4.0 pF. FREQUENCY VS.
