CS53L30

3 Characteristics and Specifications

8.Hand-off timing for multidevice

systems (SHIFT_LEFT = 1).

When SHIFT_LEFT = 1, it is

recommended to insert an empty

slot between devices on the

TDM bus to prevent contention

possibilities.

9.In Master Mode, the output sample rate follows the MCLK rate, per Section 4.6.5. MCLK deviations from the nominal supported rates are passed

directly to the output sample rate by the same factor (e.g., a +100 ppm offset in the frequency of MCLK becomes a +100 ppm offset in FSYNC).

10.“n” refers to number of SCLK cycles programmed in LRCK_TPWH[10:3] | LRCK_TPWH[2:0] (see p. 51) when

LRCK_50_NPW (see p. 51) is set;

otherwise, tFSYNC has a 50% duty cycle.

Table 3-13. Switching Specifications—I2C Control Port

Test conditions (unless specified otherwise): Fig. 2-1 shows CS53L30 connections; GNDA = GNDD = 0 V; all voltages are with respect to ground;

Parameters can vary with VA, typical performance data taken with VA = 1.8 V, VP = 3.6 V, min/max performance data taken with VA = 1.8V, VP = 3.6V;

TA = +25°C; logic 0 = ground, logic 1 = VA; input timings are measured at VIL and VIH thresholds, and output timings are measured at VOL and VOH

thresholds (see Table 3-14).

Parameter 1,2

1.All specifications are valid for the signals at the pins of the CS53L30 with the specified load capacitance.

2.I2C control port timing.
