Regarding the new DSP version of the Degen DE1103, SWLing Post contributor, Andi_84, writes:

I’ve opened [my Degen DE1103] and checked the semiconductors inside.

It’s definitely based on a Silicon Labs chip (Si4735-D60).

1) Display PCB
Valence Tech AP651 “LCD AND KEYBOARD CONTROLLER”: http://www.valencetech.com/products.php?prodID=ap651&type=ics
Datasheet: http://www.valencetech.com/doc/AP651/DS_AP651-Rev0.1.02.pdf

2) Main PCB

a) Silicon Labs Si4735-D60 “AM/FM/SW/LW Radio Receiver IC”: http://www.silabs.com/products/audio/fm-am-receiver/Pages/si473435.aspx
-> Chip is even capable of RDS, but it’s unfortunately not implemented in the DE1103
And, FM range covers down to 64MHz, while the DE1103 goes only down to 76MHz
Datasheet: https://www.silabs.com/Support%20Documents/TechnicalDocs/Si4730-31-34-35-D60.pdf

b) ST Micro STM8L152C6T6 “Ultra-low-power 8-bit MCU with 32 Kbytes Flash, 16 MHz CPU, integrated EEPROM”
Datasheet: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00240181.pdf

c) China Hua Jing Electronics CD1622CB “110mw X 2 Dual-channel audio power amplifier”
-> Looks like a “chinese version” of the Sony CXA1622M
Datasheet: http://www.datasheet.hk/view_download.php?id=1039877&file=0024%5Ccd1622cb_203207.pdf

d) LM358 “Low-Power, Dual-Operational Amplifiers”
Datasheet: http://www.ti.com/lit/ds/symlink/lm158-n.pdf

Many thanks, Andi!  These photos are excellent and certainly give us more insight into the new Degen DE1103 design.

I’m very curious how this new DE1103 compares with other DSP portables on the market.
