説明
The 650-12 is a low cost, low-jitter, high-performance clock synthesizer designed to produce fixed clock outputs of 13.5 MHz and 27.0 MHz, and four selectable clock outputs: two Processor Clocks (PCLK1) and PCLK2), an Audio Clock, and a Communications Clock (CCLK). Using analog Phase-Locked Loop (PLL) techniques, the device uses a 27.0 MHz clock or fundamental crystal to produce clocks ideal for Digital Video/MPEG-based applications.
