Note:
1. OVDD = 1.7 V; Vout = 1.42 V. (Vout-OVDD)/IOH must be less than 21 W for values of Vout between OVDD and OVDD-0.28 V.
2. OVDD = 1.7 V; Vout = 280 mV. Vout/IOL must be less than 21 W for values of Vout between 0 V and 280 mV. Simulation circuit
for parameters Voh and Vol for I/O cells is below
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:
wcs model, 1.65 V, and 105 °C.
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
this document.
