DIGITAL CHARACTERISTICS (T
A = -40 to 85 °C; power supply pins within ±5% of nominal.)
Notes: 23. Digital inputs are designed for CMOS logic levels.
24. Digital outputs are TTL compatible and drive CMOS levels into a CMOS load.
SWITCHING CHARACTERISTICS (T
A = -40 to 85 °C; power supply pins within ±5% of nominal;
Inputs: Logic 0 = 0 V, Logic 1 = DV+.)
Notes: 25. The maximum burst rate of a gapped TCLK input clock is 8.192 MHz. For the gapped clock to be
tolerated by the CS61584A, the jitter attenuator must be switched to the transmit path of the line
interface. The maximum gap size that can be tolerated on TCLK is 28 UIp-p.
26. RCLK duty cycle may be outside the specified limits when the jitter attenuator is in the transmit path
and when the jitter attenuator is employing the overflow/underflow protection mechanism.
27. At max load of 50 pF.
