The RO2156E 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 868.95 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.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1.
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.
2.
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.
3.
One or more of the following United States patents apply: 4,454,488 and
4,616,197.
4.
Typically, equipment utilizing this device requires emissions testing and
government approval, which is the responsibility of the equipment
manufacturer.
5.
Unless noted otherwise, case temperature TC = +25°C±2°C.
6.
The design, manufacturing process, and specifications of this device are
subject to change without notice.
7.
Derived mathematically from one or more of the following directly
measured parameters: fC, IL, 3 dB bandwidth, fC versus TC, and CO.
8.
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 T
O is
approximately equal to the specified resonator TO.
9.
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 -0.05pF.
10.
Tape and Reel Standard for ANSI / EIA 481.
