10697fa

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: Phase Deviation = 1/2(Phase at 0Hz – Phase at fCUTOFF) – (Phase

at 0Hz – Phase at 0.5fCUTOFF)

Phase at 0Hz = 180° (guaranteed by design)

ELECTRICAL CHARACTERISTICS The l denotes speciﬁcations which apply over the full operating

temperature range. fCUTOFF is the ﬁlter’s cutoff frequency and is equal to fCLK/25. The fCLK signal level is TTL or CMOS (max clock rise

or fall time ≤ 1μs), RL = 10k, TA = 25°C, unless otherwise speciﬁed. All AC gains are measured relative to the passband gain.

Example: An LTC1069-7 has Phase at 0.5fCUTOFF = – 30.5° and Phase at

fCUTOFF = –235°.

Passband Phase Deviation from Linear Phase

= 1/2[180° – (–235°)] – [(180° – (–30.5°)] = –3°
