PIN DESCRIPTIONS

The DSC60xxB is a highly configurable device and can be factory programmed in many different ways to meet the

choose the necessary options, create the final part number, data sheet, and order samples. The descriptions of the pins

are listed in Table 2-1.

An explanation of the different options listed in Table 2-1 follows.

2.1

Pin 1

This is a control pin and may be configured to fulfill one

of six different functions. If not actively driven, a 10 kΩ

pull-up resistor is recommended.

2.1.1

OUTPUT ENABLE (OE)

Pin 1 may be configured as OE. Oscillator output may

be turned on and off according to the state of this pin.

2.1.2

STDBY

Pin 1 may be configured as Standby. When the pin is

low, both output buffer and PLL will be off and the

device will enter a low power mode.

2.1.3

FREQUENCY SELECT (FS)

Pin 1 may be configured as FS. The output may be set

to one of two pre-programmed frequencies. The output

clock frequencies can only be set to either kHz or MHz.

A combination of kHz and MHz cannot be set.

2.2

Pins 2 through 4

Pins 2 and 4 are the supply terminals, GND and VDD

respectively. Pin 3 is the clock output, programmable to

Standard and Low Drive strength settings. Visit
