PLL1708DBQ

PLL1708DBQ Description

The PLL1708DBQ 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 (crystal or external clock) and delivering CMOS-compatible outputs. Operating within a 2.7V to 3.6V supply range, it achieves a maximum frequency of 36.87MHz, making it suitable for low-power, high-accuracy systems. The device is RoHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited), ensuring reliability in industrial and commercial environments.

PLL1708DBQ Features

• Flexible Clock Generation: Combines divider (Yes) and multiplier (No) functionality for precise frequency synthesis.
• Wide Input Compatibility: Accepts CMOS or crystal inputs, simplifying system design.
• Low-Voltage Operation: Optimized for 2.7V–3.6V supplies, ideal for battery-powered and portable devices.
• High Output Drive: Six CMOS outputs with robust signal integrity for driving multiple loads.
• Industrial Robustness: MSL 1 rating and -40°C to 85°C operating range ensure reliability in harsh conditions.
• Space-Efficient: 20-SSOP surface-mount package reduces PCB footprint.
