Note:
1. OVDD = 1.7 V; V
2. OVDD = 1.7 V; V
3. Vin(dc) specifies the allowable DC excursion of each differential input
4. Vid(dc) specifies the input differential voltage required for switching. The minimum value is equal to Vih(dc) - Vil(dc).
5. Vtt is expected to track OVDD/2.
6. Minimum condition: BCS model, 1.95 V, and –40 °C. Typical condition: typical model, 1.8 V, and 25 °C. Maximum condition:
7. Typical condition: typical model, 1.8 V, and 25 °C. Maximum condition: BCS model, 1.95 V, and 105 °C.
8. The JEDEC SSTL_18 specification (JESD8-15a) for a SSTL interface for class II operation supersedes any specification in
3.5.2
