Clock generators for embedded communications
AMI Semiconductor (AMIS) has expanded its clock generator product line with a broad family of low-cost 1- and 2-phase-lock loop (PLL) clock ICs.
Clock generator saves space in portable designs
AMI Semiconductor (AMIS) has introduced a low-cost clock generator that will save space and reduce component count in high-performance MPEG-2 applications such as DVD players.
The device is also suitable for use in a wide range of industrial applications.
The AMIS-X660 provides differential transmit/receive capability between the bus and the CAN protocol controller.
Suitable for use in 12 and 24V systems, it is able to achieve transmission rates of up to 1Mbaud.
The electromagnetic susceptibility (EMS) is top of the list of device features, the level of immunity is extremely high; this is due to the wide common mode voltage range of the receiver inputs (+/-35V).
Similarly, the transceiver has extremely low electromagnetic emission (EME) that results from the excellent matching of output signals; this feature negates the need for a common-mode-choke.
The transceivers are protected against the transients typical in automotive environments.
The CANbus remains undisturbed should an unpowered AMIS-X660 node be connected to the bus network.
Built-in protection features of the AMIS-X660 include: a thermal protection circuit that triggers shutdown at approximately 160C; 45V load dump protection; and continuous short circuit protection to supply and ground.
A transmit data (TXD) dominant time-out function is also provided to prevent bus lines being driven to a permanent dominant state; a problem that can result in the blocking of all network communication.
Commenting on the launch of the AMIS-X660 CAN transceiver, Karl Britton, Product Manager at AMIS said: "AMIS is a traditionally strong player in the automotive, industrial and medical ASIC market, we are now able to complement this with targeted ASSPs".
He continued: "The AMIS-X660 has class leading, reliable performance and outstanding EMC features.
It will prove to be a useful component for design engineers, particularly those involved in the rapid growth area of in-car networking factory automation, and building security and management".
The AMIS-X660 is supplied in an SO-8 package and has an operating temperature range of -40 to +125C.
