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 frequency fC is the frequency of minimum IL with the resonator in the specified test fixture in a 50 test system with VSWR ≤ 1.2:1.
3.
One or more of the following United States patents apply: 4,454,488; 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 ].
9.
This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for reference only. The capacitance CO is the
measured static (nonmotional) capacitance between either pin 1 and ground or pin 2 and ground. The measurement includes case parasitic capacitance.

The RS1033-1 is a two-port surface-acoustic-wave (SAW) resonator in a low-profile
TO39 case. It provides reliable, fundamental-mode, quartz frequency stabilization of
fixed-frequency oscillators operating at or near 668 MHz. Typical applications include
the second LO in CATV set-top convertors with channel 2 output.
