San Jose, Calif. - Atmel Corp. has a radio-controlled clock receiver that it says can be used for all time-code applications. The T4227, manufactured on a bipolar process, offers a reception frequency range from 40 to 120 kHz, which should be sufficient to accommodate future transmitters, according to product-marketing manager Roland Polonio.
Polonio claimed that the part represents a 3-dB improvement over other clock receivers and that it reduces the external components required to an antenna, a crystal and two capacitors.
The part's operating range extends to 1.1 volts, suiting it for battery-driven applications. It comes in an SSO16 and is priced from $1.90 in 10,000-piece volumes.
