MAXIM DS3231 Extremely Accurate I2C-Integrated RTC/TCXO/Crystal Manual

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accu- rate timekeeping when main power to the device is inter- rupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. The DS3231 is available in commercial and industrial temperature ranges, and is offered in a 16-pin, 300-mil SO package. The RTC maintains seconds, minutes, hours, day, date, month, and year information. The date at the end of the month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Two programmable time-of- day alarms and a programmable square-wave output are provided. Address and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage refer- ence and comparator circuit monitors the status of VCC to detect power failures, to provide a reset output, and to automatically switch to the backup supply when nec- essary. Additionally, the RST pin is monitored as a pushbutton input for generating a µP reset. Applications Servers Utility Power Meters Telematics GPS

MAXIM DS26303 3.3V E1/T1/J1 Short-Haul Octal Line Interface Unit Manual

The DS26303 is an 8-channel short-haul line interface unit (LIU) that supports E1/T1/J1 from a single 3.3V power supply. A wide variety of applications are supported through internal termination or external termination. A single bill of material can support E1/T1/J1 with minimum external components. Redundancy is supported through nonintrusive monitoring, optimal high-impedance modes, and configurable 1:1 or 1+1 backup enhancements. An on-chip synthesizer generates the E1/T1/J1 clock rates by a single master clock input of various frequencies. Two clock output references are also offered.

MAXIM MAX748A/MAX763A 3.3V Step-Down Current-Mode PWM DC-DC Converters Manual

The MAX748A/MAX763A is a 3.3V output CMOS step-down switching regulator. The MAX748A accepts inputs from 3.3V to 16V and delivers up to 500mA. The MAX763A accepts inputs between 3.3V and 11V and delivers up to 500mA. Typical efficiencies are 85% to 90%. Quiescent supply current is 1.4mA (MAX763A), and only 0.2µA in shutdown. Pulse-width-modulation (PWM) current-mode control provides precise output regulation and excellent transient responses. Output voltage accuracy is guaranteed to be ±5% over line, load, and temperature variations. Fixed-frequency switching allows easy filtering of output ripple and noise, as well as the use of small external components. A 22µH inductor works in most applications, so no magnetics design is necessary. The MAX748A/MAX763A also feature cycle-by-cycle cur- rent limiting, overcurrent limiting, undervoltage lockout, and programmable soft-start protection. The MAX748A is available in 8-pin DIP and 16-pin wide SO packages; the MAX763A comes in 8-pin DIP and SO packages.
