Such a buffer is intended for use in a – Crystal Frequencies Supported Are From variety of mobile and wired infrastructure, data 8 MHz to 50 MHz communication, computing, low-power medical – Differential and Single-Ended Input imaging, and portable test and measurement Frequencies Supported Are up to 200 MHz applications. When the input is an illegal level, the output is at a defined state. The core can be set to • 10 Single-Ended LVCMOS Outputs. The 2.5 V or 3.3 V, and output can be set to 1.5 V, 1.8 V, outputs can operate at 1.5-V, 1.8-V, 2.5-V or 2.5 V or 3.3 V. The CDCLVC1310 can be easily 3.3-V Power-Supply Voltage. configured through pin programming. The overall – LVCMOS Outputs Operate up to 200 MHz additive jitter performance is 25 fsRMS (typ). The CDCLVC1310 is packaged in a small 32-pin 5-mm × – Output Skew Is 30 ps (typ) 5-mm QFN package. – Total Propagation Delay Is 2 ns (typ) – Synchronous and Glitch-Free Output Enable Is Available • Offered in QFN-32 5-mm × 5-mm Package With Industrial Temperature Range of –40°C to 85°C • Crystal Input Can Be Overdriven With LVCMOS Signal up to 50 MHz 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
