Paṭiccasamuppāda In Saccapabba

In saccapabba of mahāsatipaṭṭhānasutta:

• Jāti is "khandhānaṃ patubhāvo" and "āyatanānaṃpaṭilābho".

1. Khandhānaṃ patubhāvo included viññāṇa-khandha.
1. Viññāṇa-khandha is viññāṇa-paṭiccasamuppāda.
2. Rūpa-paṭiccasamuppāda is rūpa-khandha. 
3. Nāma-paṭiccasamuppāda is vedanā-, saññā-, saṇkhāra-khandha (cetana, phassa, manasikāra). (see: sammādiṭṭhisuttaṃ)
2. Those nāma- and rūpa-paṭiccasamuppāda are piyarūpa/sātarūpa.
3. 60 piyarūpa/sātarūpa: 6 outer āyatana, 6 āyatana-paṭiccasamuppāda, 6 viññāṇa-paṭiccasamuppāda, and 42 nāma-paṭiccasamuppāda  (6 vedana-paṭiccasamuppāda, 6 saññā-khandha, 6x5 saṇkhāra-khandha [phassa-paṭiccasamuppāda, cetanā-paṭiccasamuppāda, vitakka, vicāra, taṇhā-paṭiccasamuppāda]).

So jāti-paṭiccasamuppāda is viññāna-paṭiccasamuppāda.

The difference is:

Jhāti is 5 khandha. So jāti is a conclusion of viññāna, nāma+rūpa, āyatana, phassa, vedanā, taṇhā, upādāna and bhavā-paṭiccasamuppāda.

But viññāṇa-paṭiccasamuppāda is an explanation of jhāti.
