Low-Power ICs Support Per-Channel Enable Controls
Mon, 09/22/2008 - 12:45pm
STMicroelectronics announces six devices in a series of clock-distribution ICs that provide per-channel output-enable controls for precision clock management in embedded and handheld applications. The two-channel STCD1020, three-channel STCD1030 and four-channel STCD1040 save component count, board complexity and 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. Designed for transmission of a single-ended sine-wave or square-wave in the range 10 to 52 MHz, these clock-distribution ICs also integrate an AC coupling capacitor to further minimize external components.
