Chipset
The platform chipset consists of the JUNO Baseband/RF ASIC, LOVIISA PMU ASIC, and BT/FM module.
The JUNO with a companion Loviisa MU combines application processor, RF transceiver, and power
management with audio, 2.0 Mpixel camera, dual LCDs, and extensive peripheral and accessory interfaces
(keypad, USB, SIM, UART, SPI, µSD).
Key components
All power supplies required by the D2800 "Juno" are provided by the N2201 "Loviisa" PMU.
The D2800 "Juno" requires two external clocks for proper operation. A 32 kHz clock supplied by the N2201
"Loviisa" PMU and a 26 MHz clock which is frequency multiplied internally and used throughout the device.
The integrated RF in the D2800 "Juno" only requires external SAW filters (Z7500, Z7501) and a GSM/EDGE FEM
for transmission (N7500).
The N2201 "Loviisa" only requires a 32 kHz clock for proper operation.
