4 / 74 page Si2457/34/15/04 4 Rev. 1.0 1. Electrical Specifications Table 1. Recommended Operating Conditions Parameter1 Symbol Test Condition Min2 Typ Max2 Unit Ambient Temperature TA F-Grade 0 25 70 °C Si2457/34/15/04 Supply Voltage, Digital3 VD 3.0 3.3 3.6 V Notes: 1. The Si2457/34/15/04 specifications are guaranteed when the typical application circuit (including component tolerance) and any Si2457/34/15/04 and any Si3018 are used. See "2. Typical Application Schematic" on page 10. 2. All minimum and maximum specifications are guaranteed and apply across the recommended operating conditions. Typical values apply at nominal supply voltages and an operating temperature of 25 °C unless otherwise stated. 3. The digital supply, VD, operates from 3.0 to 3.6 V. The Si2457/34/15/04 interface supports 5 V logic (CLKIN/XTALI supports 3.3 V logic only). Table 2.
