RTC operates at 55nA

Sub-threshold CMOS chip firm Ambiq is offering real-time clocks (RTCs) down to 55nAtyp (3V) with a 32.786kHz crystal. Sub-threshold operation is a way to reduce CMOS power consumption – at the expense of far greater process and temperature-dependent behaviour. “When compared to a typical circuit operating…

TI designs 12V driver ICs for quiet motors

Texas Instruments says it has simplified the tuning of stepper and brushed DC motors with its latest 12V motor drivers. The device, designated the DRV8846, incorporates an adaptive current control technology that automatically tunes the motor.  smooth and quiet motion. Adaptive current regulation dynamically changes current regulation schemes according to…

CMOS logic at 230°C

Grenoble-based X-REL Semiconductor has introduced a high-temperature replacement for 54HC and 74HC logic gates. Called XTR54000, the chip is “able to reliably operate well below and above the -60°C +230°C temperature range, and for five years at +230°C. Determined by two logic inputs, the…

Linear retunes low noise fractional-N PLL

Linear Technology has introduced a fractional-N phase-locked loop (PLL) with 6GHz-plus integrated voltage-controlled oscillator (VCO). The LTC6948 has a fourth order delta-sigma modulator that employs noise-shaping techniques to minimise noise contribution without creating the fractionalisation spurs typically found with fractional-N PLLs. The chip…

PCIM: Analog cuts power of quad-channel clock translator

Analog Devices has introduced at PCIM in Nuremberg today a multi-service adaptive quad-channel clock translator with clock multiplier, which provides jitter cleanup and synchronisation for synchronous optical networks (SONET/SDH). Its embedded cross-point switch at the input provides greater flexibility and lower cost of ownership than maintaining…

Programmable clock's RMS phase jitter is just 0.7ps

Integrated Device Technology has introduced a range of programmable clock generators with RMS phase jitter less than 0.7 picoseconds over the full 12kHz to 20MHz range. As a result the devices meet the jitter requirements of PCI Express Gen 1/2/3, USB 3.0, and 1G/10G Ethernet…
