The DS1091L is a low-cost clock generator that is factory-trimmed to output frequencies from 130kHz to 66.6MHz with a nominal accuracy of ±0.25%. The device can also produce a center- or down-dithered spread-spectrum output with pin-selectable dither magnitude and rate. Assembled in an 8-pin µMAX®package, 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).ApplicationsAutomotive InfotainmentIndustrial ControlLCD DisplaysPOS TerminalsPrinters

The DS1094L is a silicon oscillator that generates four multiphase, spread-spectrum, square-wave outputs. Frequencies between 2MHz and 31.25kHz can be output in either two, three, or four-phase mode. The internal master oscillator can be dithered by either 0, 2, 4, or 8%; to reduce the amount of peak spectral energy at the fundamental and harmonic clock frequencies. This significantly reduces the amount of electromagnetic interference (EMI) radiation that is generated at the system level. The DS1094L is ideally suited as a clock generator for switched-mode power supplies. The outputs generated by the DS1094L are used by DC-DC circuitry to efficiently shift voltages either up or down. The DS1094L can be programmed using the I²C-compatible, 2-wire serial interface to select the output frequency, number of clock phases, and dither rate, or optionally it can be shipped from the factory custom programmed.ApplicationsPrintersServersSwitch-Mode Power Supplies

The DS1110 delay line is an improved replacement for the DS1010. It has ten equally spaced taps providing delays from 5ns to 500ns. The devices are offered in a standard 16-pin SO, or 14-pin TSSOP. The DS1110 series delay lines provide a nominal accuracy of ±5% or ±2ns, whichever is greater, at 5V and +25°C. The DS1110 reproduces the input logic state at the tap 10 output after a fixed delay as specified by the dash number extension of the part number. The DS1110 is designed to produce both leading- and trailing-edge delays with equal precision. Each tap is capable of driving up to ten 74LS type loads. Dallas Semiconductor can customize standard products to meet special needs.ApplicationsAutomated Test Equipment (ATE)Communication SystemsMedical DevicesPC Peripheral Devices
