Electrical Characteristics
4.1.4
The i.MX53xD device has four external input system clocks, a low frequency (CKIL), a high frequency
(XTAL), and two general purpose CKIH1 and CKIH2 clocks.
The CKIL is used for low-frequency functions. It supplies the clock for wake-up circuit, power-down real
time clock operation, and slow system and watch-dog counters. The clock input can be connected to either
external oscillator or a crystal using internal oscillator amplifier.
The system clock input XTAL is used to generate the main system clock. It supplies the PLLs and other
peripherals. The system clock input can be connected to either external oscillator or a crystal using internal
oscillator amplifier.
CKIH1 and CKIH2 provide additional clock source option for peripherals that require specific and
accurate frequencies.

By default, the VDD_ANA_PLL is driven from internal on-die 1.8 V linear regulator (LDO). In this case there is no need driving
this supply externally. A bypass capacitor of minimal value 22 μF should be connected to this pad in any case whether it is
driven internally or externally. Use of the on-chip LDO is preferred. See i.MX53 System Development User’s Guide.
After fuses are programmed, Freescale strongly recommends the best practice of reading the fuses to verify that they are
written correctly. In Read mode, VDD_FUSE should be floated or grounded. Tying VDD_FUSE to a positive supply (3.0 V–3.3
V) increases the possibility of inadvertently blowing fuses and is not recommended in read mode.
If not using TVE module or other pads in this power domain for the product, the TVDAC_DHVDD and TVDAC_AHVDDRGB
can remain floating.
GPIO pad operational at low frequency
The analog supplies should be isolated in the application design. Use of series inductors is recommended.
VDD_REG is power supply input for the integrated linear regulators of VDD_ANA_PLL and VDD_DIG_PLL when they are
configured to the internal supply option. VDDR_REG still has to be tied to 2.5 V supply when VDD_ANA_PLL and
VDD_DIG_PLL are configured for external power supply mode although in this case it is not used as supply source.
Lifetime of 21,900 hours based on 95 C junction temperature at nominal supply voltages.
