DS1091L

The DS1091L is a low-cost clock generator that is factorytrimmed to output frequencies from 130kHz to 66.6MHz with a nominal accuracy of ±0.25%. Assembled in an 8-pin MAXpackage, the DS1091L is designed to operate with a 3.0V to 3.6V power supply over the automotive temperature range (-40°C to +125°C). The device can also produce a centeror down-dithered spread-spectrum output with pin-selectable dither magnitude and rate.

The features of DS1091L can be summarized as (1)spread-spectrum clock output from 130kHz to 66.6MHz; (2)operating temperature range of -40°C to +125°C; (3)accuracy of ±1.75% across temperature and voltage; (4)factory trimmed; (5)center-dithered (DS1091LA)or down-dithered (DS1091LB)spread-spectrum output; (6)pin-selectable center-dither magnitude of 0%, ±1%, ±2%, or ±4%; (7)pin-selectable down-dither magnitude of 0%, -2%, -4%, or -8%; (8)pin-selectable dither rate; (9)3.0V to 3.6V supply operation; (10)lead-free 8-pin MAX package.

The absolute maximum ratings of DS1091L are (1)voltage on VCC relative to ground: -0.5V to +6.0V; (2)voltage on DR, SEL0, SEL1 relative to ground*: -0.5V to (VCC + 0.5V); (3)operating temperature range: -40°C to +125°C; (4)storage temperature range: -55°C to +125°C; (5)soldering temperature: See J-STD-020 Specification.
