| September 2006 rev 0.1 Multi-Output Clock Generator Features Product Description * Generates multiple clock outputs from an inexpensive 27MHz crystal . * Frequency outputs: PCS1P2857A * * * * * * * CLK1 : 27 MHz CLK2 : 24 MHz CLK3 : 14.31818 MHz CLK4 : 14.31818 MHz CLK1 : 27 MHz CLK2 : 24 MHz CLK3 : 28.322 MHz PCS1P2857A/B The PCS1P2857A/B is a versatile multi output clock generator. The PCS1P2857A/B uses the latest PLL technology. The four Clock outputs are generated using an inexpensive 27MHz Crystal. The accuracy of the 27MHz Input Clock should be within 50ppm. The outputs consist of 24 MHz, 14.31818 MHz, and 28.322 MHz clocks together with a 27 MHz reference clock. The device operates from a Supply Voltage of 3.3V5%V. The device is available in a 8 pin SOIC and 8 pin TSSOP JEDEC package. * Frequency outputs: PCS1P2857B * Operates with a 3.3V 5%V Supply Voltage * Available in 8 -pin SOIC and 8 -pin TSSOP. Application PCS1P2854A/B is targeted for use in HDTV digital video. Block Diagram VDD CLK2 XIN XOUT Crystal Oscillator PLL CLK3 CLK4 CLK1 GND PulseCore Semiconductor Corporation 1715 S.
