CS42L73
DIGITAL INTERFACE SPECIFICATIONS AND CHARACTERISTICS
Test Conditions (unless otherwise specified): Connections to the CS42L73 are shown in the “Typical Connection Diagram” on
page 17; GND = AGND = PGND = CPGND = DGND = 0 V; all voltages are with respect to ground (GND); VA = VL = 1.80 V, VP
= 3.70 V; T
A
= +25 C.
Notes:
49. Specification is per pin.
50. Specification includes current through internal pull up/down resistors, where applicable (as defined in section “Digital
Pin/Ball I/O Configurations” on page 16).
51. The minimum values of the pull-up resistors R
P
and R
P_I
(as shown in the “Typical Connection Diagram” on page 17
and specified in “Digital Interface Specifications and Characteristics” on page 35) are determined using the maximum
level of VL, the minimum sink current strength of their respective output, and the maximum low-level output voltage (V
OL
in “Digital Interface Specifications and Characteristics” on page 35). The maximum values of R
P
and R
P_I
may be de-
termined by the how fast their associated signals must transition (e.g., the lower the value of R
P
, the faster the I²C bus
will be able to operate for a given bus load capacitance). Refer to “Switching Specifications—Control Port” on page 40
and to the I²C bus specification (see section “References” on page 137) for more details.
