4.12.14.2 MediaLB (MLB) Controller AC Timing Electrical Specifications
This section describes the timing electrical information of the MediaLB module. Figure 81 show the
timing of MediaLB 3-pin interface, and Table 73 and Table 74 lists the MediaLB 3-pin interface timing
characteristics.
Figure 81. MediaLB 3-Pin Timing
Ground = 0.0 V; Load Capacitance = 60 pF; MediaLB speed = 256/512 Fs; Fs = 48 kHz; all timing
parameters specified from the valid voltage threshold as listed below; unless otherwise noted.
