ICS650R-12

DATASHEET ICS650-12 MPEG CLOCK SYNTHESIZER Description Features The ICS650-12 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. • Packaged in 20-pin tiny SSOP (QSOP) • Available in RoHS 5 (green) or RoHS 6 (green and lead free) compliant package • Input frequency of 27.0 MHz • Zero ppm synthesis error in output clocks • Provides fixed 13.5 MHz and 27.0 MHz. Also provides • • • two selectable processor clocks, one audio clock, and one communications clock.

These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
