Serial Port DC and Timing Specifications
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: LTC6602C and LTC6602I are guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 3: LTC6602C is guaranteed to meet specified performance from
0°C to 70°C. The LTC6602C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. The LTC6602I is guaranteed to meet the
specified performance limits from –40°C to 85°C.
Note 4: This test measures the internal oscillator accuracy (deviation from
the f
CLK
equation). Variations in the internal oscillator frequency cause
variations in the filter cutoff frequency. See the “Applications Information”
section.
Note 5: 1.57MHz is the equivalent noise bandwidth of a 1MHz 1st order
RC lowpass filter.
Note 6: Guaranteed by design, not subject to test.
Note 7: To conform to the Logic IC standard, current out of a pin is
arbitrarily given a negative value.
