Crystal Characteristics Test conditions (unless specified otherwise): GNDD = GNDCP = GNDA = 0 V; voltages are with respect to ground; VP = 3.6 V, VCP = VA = 1.8 V, VL = VD = 1.8 V; TA = +25°C Parameters 1 1.Refer to Section 5.3 for supported crystal options. Symbol Minimum Typical Maximum Units Crystal oscillator frequency fXTAL 22.57 22.5792/ 24.576 24.58 MHz Crystal load capacitance CL_XTAL 5— 8 pF Equivalent series resistance esrXTAL —— 100 Startup time tXTAL_pup —— 8 ms Shunt capacitance CO —— 0.8 pF Maximum drive level — 200 — — µW Table 3-12. Power-Supply Rejection Ratio (PSRR) Characteristics Test conditions (unless specified otherwise): Fig. 2-1 shows CS4399 connections; input test signal held low (all zero data); GNDA = GNDL = GNDCP = 0 V; voltages are with respect to ground; VL = VA = VD = 1.8 V, VP = 3.6 V; When testing PSRR, PCM input test signal held low (all zero data); TA = +25°C; PCM_AMUTE = 0. Parameter 1 1.PSRR test configuration: Typical PSRR can vary by approximately 6 dB below the indicated values.
