PCS1P2858A May 2008 rev 0.2 Multi-Output Clock Generator Features Product Description • Generates multiple clock outputs from an inexpensive The PCS1P2858A is a versatile multi output clock generator. The PCS1P2858A uses the latest PLL 27MHz crystal . • Multiple Clock outputs: technology. The six Clock outputs are generated using • 27MHz Reference clock an inexpensive 27MHz Crystal. The accuracy of the • 27MHz Reference clock 27MHz Input Clock should be within ±50ppm. The • 10MHz outputs consist of 24.576MHz, 24 MHz, 10MHz, and • 24MHz 28.322 MHz clocks together with two 27 MHz reference • 28.322MHz clock. The OE tri-states all the clocks when disabled. • 24.576MHz The device operates from a Supply Voltage of • Supply Voltage:3.3V ± 5%V 3.3V±5%V. The device is available in a 16-pin TSSOP • 16 pin TSSOP Package JEDEC package. • Commercial Temperature range • Low-power CMOS process.
