1 / 5 page  DSC2311KI2-R0055 Crystal-less™ Configurable Clock Generator General Description DSC2311KI2-R0055 is a crystal-less clock generator that is factory configurable to simultaneously output two separate frequencies from 2.3 to 170MHz. The clock generator uses proven silicon MEMS technology to provide low jitter and high frequency stability across a wide range of supply voltages and temperatures. By eliminating the external quartz crystal, crystal-less clock generators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of consumer electronics, communications, and storage applications. DSC2311KI2-R0055 has an output enable/disable feature allowing it to disable the outputs when OE is low. The device is available in a space-saving 6-pin 2.5mm x 2.0mm TDFN package that needs only a single external bypass capacitor. This requires a PCB footprint equivalent to that of a 1.0mm x 1.0mm crystal-based clock generator. Features • Two simultaneous LVCMOS outputs: - 16MHz - 27.034483MHz • Low RMS phase jitter: <1ps (typical) • ±25ppm frequency stability • -40°C to +85°C industrial temperature range • High supply noise rejection: -50dBc • High shock & vibration immunity - Qualified to MIL-STD-883 • High reliability - 20x higher MTBF than crystal-based clock generator designs • Programmable output strength for EMI reduction and signal integrity optimization • Supply range of 2.25 to 3.6V • AEC-Q100 automotive qualified • 6-pin 2.5mm x 2.0mm TDFN package Applications • Consumer Electronics • Camera and Imaging Modules • Home Automation • Industrial and Power Conversion • Mobile Communications, Internet, and Sensor Devices • Solid State, Hard Drive, and Flash Drive Storage • Automotive Block Diagram Control Circuitry MEMS PLL ÷ M1 CLK0 ÷ M2 CLK1 16MHz LVCMOS 27.034483MHz LVCMOS OE ClockWorks is a registered trademark of Microchip Technology Inc.
