Polycom P008 Embedded ISM43341 SIP Application Module – User Guide
Circuit Description
The Polycom P008 ISM43341 single-chip device provides a small form-factor solution with minimal external
components to drive down cost for mass volumes, and allows for handheld device flexibility in size, form,
and function. Comprehensive power management circuitry and software ensure the system can meet the
needs of high mobile devices that require minimal power consumption and reliable operations.
PCB Integration
SDIO/I2S/UART Interface/Connection to Motherboard
The RealPresence Trio radio module PCB employs a 40-pin flex circuit socket to connect to a motherboard
40-pin flex circuit cable. This interface is for the 3.3 VDC and 1.8Vpower sources and all necessary data
lines to communicate with the radio module.
Mounting
The radio module has two mounting holes. The module should be placed down and fastened onto a
motherboard containing two standoffs with metal screws. At the same time, the 40-pin flex cable connector
will be engaged by locking the flex connector.
Antenna
The 2.4GHz/5GHz radio module PCB antennas are mounted permanently for WiFi/BT operation. No
external WiFi/BT antennas are allowed.
The NFC antenna loop is connected via a two-pin locking connector. Only the Polycom NFC antenna loop
or equivalent is allowed.
