DC Characteristics (VDD = 1.8 V ±5%, VDDA = 3.3 V ±5%, VDDO = 1.8 V ±5%, 2.5 V ±5%, or 3.3 V ±5%, TA = –40 to 85 °C) Parameter Symbol Test Condition Min Typ Max Unit Core Supply Current IDD Si5345 — 125 185 mA Si5344 — 105 155 mA Si5342 — 105 155 mA IDDA Si5345 — 120 125 mA Si5344 — 115 120 mA Si5342 — 115 120 mA Output Buffer Supply Current IDDOx LVPECL Output4 @ 156.25 MHz —21 25 mA LVDS Output4 @ 156.25 MHz —15 18 mA 3.3 V LVCMOS5 output @ 156.25 MHz —21 25 mA 2.5 V LVCMOS5 output @ 156.25 MHz —16 18 mA 1.8 V LVCMOS5 output @ 156.25 MHz —12 13 mA Total Power Dissipation Pd Si5345 Notes 1, 6 — 880 1040 mW Si5344 Notes 2, 6 — 720 850 mW Si5342 Notes 3, 6 — 715 840 mW Notes: 1. Si5345 test configuration: 10x 3.3 V LVDS outputs enabled @156.25 MHz. Excludes power in termination resistors. 2. Si5344 test configuration: 4x 3.3 V LVDS outputs enabled @ 156.25 MHz. Excludes power in termination resistors. 3. Si5342 test configuration: 2x 3.3 V LVDS outputs enabled @ 156.25 MHz. Excludes power in termination resistors. 4. Differential outputs terminated into an AC coupled 100 load. 5. LVCMOS outputs measured into a 6 inch 50 PCB trace with 5 pF load. Measurements were made in CMOS3 mode. 6. Detailed power consumption for any configuration can be estimated using ClockBuilder Pro when an evaluation board (EVB) is not available. All EVBs support detailed current measurements for any configuration. |
