CX9VSM CRYSTAL

32 kHz to 250 kHz

Ultra-Miniature, Low Profile

Surface Mount Quartz Crystal

DESCRIPTION

Designed and manufactured in the USA, the CX9V quartz

crystal is available in frequencies from 32 kHz to 250 kHz.

Using micro-machining processes, this surface-mountable

crystal is hermetically sealed within a ultra-miniature ceramic

package to ensure high stability and low aging. Tight

calibration and custom laser tuning make the CX9V ideally

suited for all low frequency applications.

TYPICAL APPLICATION

FOR A PIERCE OSCILLATOR

SPECIFICATIONS

Specifications are typical at 25^OC unless otherwise noted.

Specifications are subject to change without notice.

The CX9 family of surface mount crystals are ideal for

small, high density, battery operated portable products. The

CX9 crystal designed in a Pierce oscillator (single inverter)

circuit provides very low current consumption and high

stability. A conventional CMOS Pierce oscillator circuit is

shown below. The crystal is effectively inductive and in a PI-

network circuit with C_Dand C_Gprovides the additional

phase shift necessary to sustain oscillation. The oscillation

frequency (f₀) is 50 to 150 ppm above the crystal’s series

resonant frequency (f_S).

Drive Level

R_Ais used to limit the crystal’s drive level by forming a

voltage divider between R_Aand C_D. R_Aalso stabilizes the

oscillator against changes in the amplifiers output

resistance (R₀). R_Ashould be increased for higher voltage

operation.

NOTE: C_Dand C_Ginclude stray layout to ground and C_S

is the stray shunt capacitance between the crystal

terminal. In practice, the effective value of C_Lwill be less

than that calculated from C_D, C_Gand C_Svalues because

of the effect of the amplifier output resistance. C_Sshould

be minimized.
