Low-Cost Fixed-Frequency EconOscillator™
General Description
The DS1088L is a low-cost clock generator that pro-
duces a square-wave output without external timing
components. The fixed-frequency oscillator is available
in factory-calibrated frequencies from 312kHz to
133MHz. The DS1088L has a power-down pin for
power-sensitive applications.
