Type Max. Supply Voltage VCC 1.7 1.8 1.9 V I/O Reference Voltage VREF 0.49 x VCC 0.50 x VCC 0.51 x VCC V1 I/O Termination Voltage VTT VREF-0.04 VREF VREF+0.04 V 2 Notes: 1. VREF is expected to equal VCC/2 of the transmitting device and to track variations in the DC level of the same. Peak-to-peak noise on VREF may not exceed +/-1percent of the DC value. Peak-to-peak AC noise on VREF may not excedd +/-2 persent of VREF. This measurement is to be taken at the nearest VREF bypass capacitor. 2. VTT in sot applied directly to the device. VTT is a system supply for signal terminaion resistors, is expected to be set equal to VREF and must track variations in the DC level of VREF. |
