This section contains the AC electrical information (including timing specifications) for the modules of
the i.MX35. The modules are listed in alphabetical order.
4.9.1
The AUDMUX provides a programmable interconnect logic for voice, audio and data routing between
internal serial interfaces (SSI) and external serial interfaces (audio and voice codecs). The AC timing of
AUDMUX external pins is hence governed by the SSI module. See the electrical specification for SSI.
4.9.2
The i.MX35 provides two CSPI modules. CSPI ports are multiplexed in the i.MX35 with other pins. See
the “External Signals and Multiplexing” chapter of the reference manual for more details.

Input pin propagation delay, 50%–50%
Input pin propagation delay, 40%–60%
Min. condition for tps: wcs model, 1.1 V, IO 1.65 V, and 105 °C. tps is measured between VIL to VIH for rising edge and between
VIH to VIL for falling edge.
Max. condition for tdit: bcs model, 1.3 V, IO 1.95 V, and –40 °C.
Max. condition for tpi and trfi: wcs model, 1.1 V, IO 1.65 V and 105 °C. Min. condition for tpi and trfi: bcs model, 1.3 V, IO 1.95 V
and –40 °C. Input transition time from pad is 5 ns (20%–80%).
