NOTE! ST_CDSP_RF_SUPPLY_TEST error code: 0x00, 0x00, 0x03, 0xBF, … means typically that

there is no VBAT_ASIC voltage coming to the Hinku RX ASIC at all or the ASIC is poorly

soldered to the PWB (All voltages that are somehow related to VBAT_ASIC are

causing errors).

Please, refer to chapter 2.11 “

Error Code Interpretation Examples”, if more information about

error code interpretation is needed.

2.10 TXC Data test (ST_TXC_DATA_TEST)

This self-test is used to check if the TXC-signal is coming correctly from Retu (N2200) to Vinku

(N7501).

Test covers: TxC power control signal, Retu (N2200), RFBUS, Vinku (N7501), VBAT_ASIC

Error code for this self-test is given in format:

• 0xyy, 0xzz, MeasResult1, MeasResult2, …

,where 0xyy, 0xzz part is the main part of the error code: 0xyyzz

Error

code

Bit mask Reason Actions

0x0001 ---------------1 TxC voltage too high with

minimum input.

Retu (or Vinku) faulty…Replace the

component.

0x0002 --------------1- TxC voltage too low with

maximum input.

3.1.1.1.1 “RF operating voltage

VBAT_ASIC?”

3.1.1.1.3 “Vinku (N7501) regulator

voltages VREG1, VREG2 ok?”

Check following step:

3.1.1.1.9 “

Is there TXC-signal coming to

Vinku ASIC (N7501)?”

Please, refer to chapter 2.11 “

Error Code Interpretation Examples”, if more information about

error code interpretation is needed.

2.11 Error Code Interpretation Examples

This chapter presents three different examples of RF error code interpretation.

2.11.1 Example 1

ST_CDSP_RX_PLL_PHASE_LOCK self test gives “Fatal” result with error code: 0x00, 0x04

This means that the total error code is 0x004 and if we look an error code table in Chapter 2.1

“

RX PLL phase lock self test” the meaning for the code is “Hinku PLL is not locked”.
