The DS1089LU-450+ is a 3.3V centre spread spectrum EconOscillator in 8 pin μMAX package. This is a clock generator that produces a spread spectrum (dithered) square wave. The DS1089LU-450+ is set to factory programmed 50MHz frequency. The DS1089L is pin-for-pin compatible with the DS1087L, however, the DS1089L dithers at equal percentages above and below the centre frequency. The user still has access to the internal frequency divider ±2% dithered output, dithering rate and programmable output power-down/disable mode through an I2C compatible programming interface. All the device settings are stored in non-volatile (NV) EEPROM allowing it to operate in stand-alone applications. The DS1089L also has power-down and output-enable control pins for power-sensitive applications.

• Supply voltage range is 2.7V to 3.6V
• Operating temperature range from -40°C to 85°C
• Centre frequency remains constant independent of dither percentage
• No external timing components required
• EMI reduction
• Dither frequency is fMOSC/4096
• User programmable down to 130KHz with divider
• Glitchless output-enable control
• Non-volatile settings
