GenevaSTMicroelectronics announced the first six devices in a series of clock-distribution ICs, which it says are the first in the market to provide per-channel output-enable controls for precision clock management in embedded and handheld applications.
According to ST, the two-channel STCD1020, three-channel STCD1030, and four-channel STCD1040 save component count, board complexity and bill-of-materials costs in multi-mode devices such as cellular handsets and M2M (machine-to-machine) communications.
By distributing a single master clock to multiple clock domains, designers can eliminate multiple individual-crystal clock sources for chipsets supporting GSM, Bluetooth, WLAN, WiMAX or other RF communications, and also set-top boxes.
The individual output-enable controls combine with a fast startup time, as well as 2.6mA typical quiescent current and 1 microamp standby current for the STCD1040, to minimize power consumption in battery-powered and embedded applications.
Pricing: $0.80 in quantities of 10,000 pieces.
