DS4000 Digitally Controlled TCXO

TEMPERATURE-COMPENSATED CRYSTAL OSCILLATOR

The DS4000 can either function as a standalone TCXO or as a digitally controlled TCXO. When used as a

standalone TCXO, the only requirements needed to function properly are power, ground, and an output. However,

the 2-wire interface must be used to tune (push and pull) the crystal.

The DS4000 is capable of supplying two different outputs, F₁and F₂.

1) F₁is the base frequency of the crystal unit inside of the device. The output type is a CMOS square wave.

2) F₂is a programmable frequency output. The frequency select register can program this output to an integer

division of the base (F₁) frequency. The duty cycle (DC) bit determines if the output is an n + 1 or a 2(n + 1)

division of F₁.

F₂FREQUENCY SELECT REGISTER (FSR) (5Dh)

Bit

Name

Default

F₂= F₁/ (FSR value + 1); with DC = 0

F₂= F₁/ [2 x (FSR value + 1)]; with DC = 1

TCXO CONTROL REGISTER (60h)

F_T

Name

Default

DC, Duty Cycle Bit: If 50% duty cycle is desired, then this bit must be set to logic 1. The default condition at

power-up is logic 0.

F_T: This bit must be programmed by the user to 0.

F₁OE, F₁Output Enable Bit: This bit allows the user to disable/enable the F₁output.

F₂OE, F₂Output Enable Bit: This bit allows the user to disable/enable the F₂output.
