RO2164E RO2164E-1 RO2164E-2 ® • • • • Ideal for European 868.35 MHz Transmitters Very Low Series Resistance Quartz Stability Complies with Directive 2002/95/EC (RoHS) Pb The RO2164E is a true one-port, surface-acoustic-wave (SAW) resonator in a surface-mount ceramic case. It provides reliable, fundamental-mode, quartz frequency stabilization of fixed-frequency transmitters operating at 868.35 MHz. This SAW is designed specifically for remote-control and wireless security transmitters operating under ETSI-ETS 300 220 in Europe and under FTZ 17 TR 2100 in Germany. 868.35 MHz SAW Resonator Absolute Maximum Ratings Rating Value Units Input Power Level 0 dBm DC Voltage 12 VDC Storage Temperature -40 to +125 °C Operating Temperature Range -40 to +125 °C SM3030-6 Case 3.0 X 3.0 Electrical Characteristics Frequency (+25 °C) Characteristic Nominal Frequency Sym RO2164E RO2164E-1 RO2164E-2 Tolerance from 868.35 MHz RO2164E RO2164E-1 RO2164E-2 fC 2,3,4,5 Minimum 868.200 868.250 868.275 Typical ∆fC Insertion Loss Quality Factor Unloaded Q 50 Ω Loaded Q Temperature Stability Turnover Temperature Turnover Frequency Frequency Temperature Coefficient Frequency Aging Absolute Value during the First Year DC Insulation Resistance between Any Two Terminals RF Equivalent RLC Model Motional Resistance Motional Inductance Motional Capacitance Shunt Static Capacitance Test Fixture Shunt Inductance Lid Symbolization (in addition to Lot and/or Date Codes) Standard Reel Quantity Reel Size 7 Inch Reel Size 13 Inch Notes IL QU QL TO fO 2,5,6 5,6,7 15 6,7,8 FTC |fA| RM LM CM CO 8000 1 5 5, 6, 7, 9 5, 6, 9 2, 7 LTEST 10 1.2 8900 TBD 25 fC Maximum 868.500 868.450 868.425 ±150 ±100 ±75 1.6 Units 35 °C kHz 0.032 <±10 1.0 12 17 19.8 1.7 1.9 TBD 516 / YWWS 500 Pieces / Reel 3000 Pieces / Reel MHz kHz dB ppm/°C2 ppm/yr MΩ Ω µH fF pF nH CAUTION: Electrostatic Sensitive Device. Observe precautions for handling. Notes: 1. 2. 3. 4. 5. 6. Frequency aging is the change in fC with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after manufacture, decreasing in subsequent years. The center frequency, fC, is measured at the minimum insertion loss point, ILMIN, with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The shunt inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically, fOSCILLATOR or fTRANSMITTER is approximately equal to the resonator fC. One or more of the following United States patents apply: 4,454,488 and 4,616,197. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the equipment manufacturer. Unless noted otherwise, case temperature TC = +25°C±2°C. The design, manufacturing process, and specifications of this device are subject to change without notice. 7. 8. 9. 10. Derived mathematically from one or more of the following directly measured parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO. Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO. The nominal frequency at any case temperature, TC, may be calculated from: f = fO [1 - FTC (TO -TC)2]. Typically oscillator TO is approximately equal to the specified resonator TO. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance CO is the static (nonmotional) capacitance between the two terminals measured at low frequency (10 MHz) with a capacitance meter. The measurement includes parasitic capacitance with "NC” pads unconnected. Case parasitic capacitance is approximately 0.05 pF. Transducer parallel capacitance can by calculated as: CP ≈ CO - 0.05 pF. Tape and Reel Standard for ANSI / EIA 481. RF Monolithics, Inc.

The two terminals are interchangeable and unnumbered. The callout NC indicates no internal connection. The NC pads assist with mechanical positioning and stability. External grounding of the NC pads is recommended to help reduce parasitic capacitance in the circuit.
