9TCS1082BNLG8

ADVANCE INFORMATION DATASHEET MOBILE ACCESS™—CLOCK SYNTHESIZER & TEMPERATURE SENSOR FOR PORTABLE DEVICES Description Features The 9TCS1082 is a highly programmable IC that integrates clock synthesizers and a temperature sensor for hardware thermal protection. Thermal Sensor The device has an ultra-low-power 32.768 kHz frequency generator to support Real Time Clocks (RTC). This device can generate the 32.768 kHz frequency up to four years of life powered by a CR2032 coin cell battery. The 9TCS1082 can output computer system clock frequencies of 25, 27, and 48 MHz which will reduce the component count on the circuit board. The 9TCS1082 includes temperature monitor function that measures through external diode. The temperature sensor is optimized to be accurate within ±1°C between the temperature range of 60°C to 100°C. This device is highly programmable through the use of I2C to set high and low limits for all the temperature channels as well as setting critical limits. The hardware limits drive dedicated Alert and Therm pins for system shutdown. The 9TCS1082 is available in a 32-pin QFN package and is available for commercial temperature range Applications • • • • • • • 9TCS1082 • One channel thermal sensor • Both H/W & S/W programmable over/under temperature • • • • • • alarms No Calibration required in application Diode failure detection Support SMBUS Alert Accuracy: ±1°C (+60°C to +100°C, remote); ±2°C (0°C to + 100°C, remote and local) Offset register for system calibration Series resistor cancellation feature System Clock PLL Synthesizers • Scalable Low Voltage VDD I/O (1.5V to 1.05V) to reduce • • • • power consumption (apply to 25MHz output) Integrated series termination resistors Selectable – Single-ended 27MHz/48MHz clock output @ VDD3.3V 2 – single ended 25MHz clock outputs (buffer out) 32.768 kHz outputs with < 1.8µA power consumption for system RTC circuit Notebook Computers Netbook Computers Smartbook Computers Consumer Portable Devices Embedded Systems Networking Equipment (i.e. Routers, Switches) Network Area Storage IDT® MOBILE ACCESS™—CLOCK SYNTHESIZER & TEMPERATURE SENSOR FOR PORTABLE DEVICES 9TCS1082 REV 0.7 012312 1 9TCS1082 MOBILE ACCESS™—CLOCK SYNTHESIZER & TEMPERATURE SENSOR FOR PORTABLE DEVICES SYNTHESIZERS Block Diagram VDD_TS Sample Current Regulator RAM 11 bits ADC Analog MUX Thermal diode ALERT# THERM# Digital Reference Voltage POR V_bat Power Switch V_3.3 SMBCLK SMBUS VDD_RTC Amplitude Control 32.768K DCO SMBDAT 32K_A_IO 32K_A Fraction N Divider VDDIO_25MA X1 25M_IO Xtal X2 25M_A VDD_25MB GND 25M_IO Ultra Low Power PLL 27/48M_IO 25M_B VDD_27M 27M_48M EN_27_48 Preferred drive strengths for single-ended outputs.
