PLL1706DBQ

Burr Brown
PLL Multi-Clock Generator IC 36.87MHz 1 20-SSOP (0.154", 3.90mm Width)
NRND424 in stock

Overview

The PLL1706DBQ is a phase-locked loop (PLL) multiclock generator designed to provide various system clocks for digital audio systems. It generates high-accuracy, low-jitter system clocks from a single crystal or external CMOS clock source, supporting common sampling frequencies for Burr-Brown DACs and ADCs.

Why Choose This Part

It offers a high integration level by providing six simultaneous clock outputs from a single 1:6 ratio, reducing the need for multiple oscillators. The device operates on a flexible 2.7V to 3.6V supply range and achieves a low-jitter output suitable for high-fidelity audio reproduction up to 36.87MHz.

Applications

Digital Audio Systems
Provides synchronized clocking for CD players, MD players, and DVD systems.
Audio DAC/ADC Timing
Generates the high-frequency master clocks (256fs, 384fs, 512fs, and 768fs) required for high-performance delta-sigma converters.
Digital Mixing Consoles
Acts as a central clocking source to ensure jitter-free digital signal processing across multiple channels.
