45.1584mhz
Overview
Product sourcing insights & recommendations
The phrase 45.1584 MHz refers to a critical high-precision clock frequency used in digital audio systems. It is a direct integer multiple ($1024 \times 44.1 \text{ kHz}$) of the standard CD sampling rate, allowing DACs to process audio with minimal timing errors known as jitter. HcixtalEeworld
Market Trends & Product Insights
* Audiophile Shift to Femto-Clocks: The market is trending toward ultra-low jitter "Femto-clocks" like the Accusilicon AS318B, which achieves jitter as low as 88 femtoseconds. These are marketed to high-end DAC users to enhance soundstage and clarity. Magnahifi
* Dual-Clock Architecture: Modern premium audio hardware now standardizes on a dual-clock setup, pairing 45.1584 MHz (for 44.1/88.2/176.4 kHz files) with 49.152 MHz (for 48/96/192 kHz files) to avoid quality loss from asynchronous resampling. HcixtalFacebook
* TCXO vs. OCXO Demand: There is rising demand for Temperature Compensated (TCXO) units in portable Hi-Fi (DAPs) and Oven Controlled (OCXO) units in professional studio master clocks for maximum thermal stability. EbayFacebook
* Competitive B2B Pricing: Standard SMD 3225 resonators are highly commoditized, priced as low as $0.05–$0.15 for bulk orders, while specialized audiophile-grade OCXO modules can range from $180 to $350+. AlibabaAlibaba
