Inside the Blackberry Q10

 

The keyboard is still alive
Touch screens  have largely changed the way we communicate by making typos socially acceptable in business communications.But in many circles, acurite tiping isstillvery important and people feel a physical keyboard helps them. Moreover, the tactile feel of a keyboard is often faster and more comfortable for the high volume user.Blackberry is here to help with their latest Q10 phone, based on their BB10 operating system and with the traditional BB keyboard design, in addition to a 3.1″ Super AMOLED capacitive display.

Taking off the back

In the interest of peeling away the onion, we are showing the back off and shields intact here. Once we pry these off, we’ll provide a list of some of the key suppliers.This (public) teardown isn’t going to be exhaustive, but the images are high resolution if you need to learn more.

 

Blackberry Q10 Teardown - Back off


The design wins

A two-sided circuit board with design wins that keep the phone on par with all the major smartphones.

On the application processor side, we have the Qualcomm MSM8960 along with the rest of the chipset. This includes the WTR1605l LTE transceiver, PM8921 PMIC, and WDC9310 audio codec.
We also have the first design win that we have cataloged this year for an Atmel touch screen controller, the MXT224s.
On the MEMS front, we have an STM accelerometer with markings DSH. We have seen this in several Apple devices recently. The InvenSense IDG3050 provides the gyroscope.
For NFC, we have the Inside Secure securead solution.
For Wi-Fi SoC, we have the venerable Broadcom BCM4334.
For antenna tuning, we have BB’s BST capacitor technology.
