PLL1705DBQ

PLL1705DBQ Description

The PLL1705DBQ from Texas Instruments is a high-performance Phase-Locked Loop (PLL) multi-clock generator designed for precision timing applications. Housed in a compact 20-SSOP package, this IC integrates a PLL with a 1:6 input-to-output ratio, supporting CMOS input/output signals and crystal oscillator inputs. Operating within a 2.7V to 3.6V supply range, it delivers a maximum output frequency of 36.87MHz, making it suitable for low-power, high-frequency systems. The device features divider/multiplier functionality (divide-only) and ensures stable clock distribution with minimal jitter. Its RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) rating make it ideal for industrial and commercial applications requiring reliable, long-term performance.
