Bluetooth technology

With the rapid growth in the demand for wireless applications, companies such as Cambridge Silicon Radio (CSR), Philips, TI & Broadcom have all produced chipsets that provide Bluetooth® wireless technology solutions. All of these chipsets require a quartz crystal to provide timing. Many of these crystals are specific to particular chipset solutions.

In addition to CSR approval Golledge supply crystals specifically customised for other leading chipsets used in Bluetooth, GPS and mobile applications, including:
