Decoder Logic Table

Design key points• Timing accuracy:

FEM is programmed through 3 GPO’s from A+/ALV trigg’d by a DVI:very low timing accuracy due to interrupts processing delay in the DSP=> Latch input (L1T) has been added to achieve required timing accuracy

• Additional attenuation of the Bluetooth band required in low band path of the diplexer to avoid Bluetooth desense due to 800MHz 3rd harmonic

Spec: 35dB, at the cost of higher insertion loss

• Return loss on PCS path:Orphee is marginal on PCS max output power. Return loss must be as

close as possible to 20dB. Spec is currently 11dB min, should be changed to 18dB min.

• Intermodulation Product power in RX band(see next slide)

Intermodulation Product Power

-15dBm @ 1710MHzCalibrated at antenna port

Spec: -103dBm to avoid receiver desense, whatever the phase at FEM inputs.Test conditions:Pwr (Ftx) = +20dBm at antennaPwr (Fint) = -15dBm at antenna (injected from the antenna toward the FEM)Measure IMP power (Frx) at RX output of the FEM

Some vendors (NEC, Eudyna) are using a DC-DC converter to increase switchessupply voltage, hence improving linearity.

Current drain

• Current drain reduction:Vdd is a permanent supply from Atlas that can’t be switched off

=> Shut-off mode to disable the decoder=> Target: 30µA max, 20µA typ.

• FEM wakeup timing (out of DSM):Goal: to wake the FEM up as late as possible to save current.

- GSM mode: wakeup 5ms prior to the first RX slot. Could be reduced to 100µs but this is not a priority since current saving is 3µA average in

DRX5 (1.12s DSM duty cycle)- WCDMA mode: 248µs prior to first RX

• DC-DC converterCould slightly increase the active current drain (extra 100-200µA).Shut-off mode current should not be impacted.
