Note: These characteristics apply only when Main Oscillator is in Bypass Mode (i.e., when MOSCEN = 0 and OSCBYPASS = 1) in the
CKGR_MOR register. See PMC Clock Generator Main Oscillator Register in
Section 29. ”Power Management Controller
(PMC)” on page 354 .
47.6 PLLA and PLLB Characteristics
The PLLA and PLLB are identical and their characteristics are described in Table 47-9 .
The following characteristics are applicable to the operating temperature range: T
A
= -40°C to 85°C and worst case of
power supply, unless otherwise specified.
Note: 1. Startup time depends on PLL RC filter. A calculation tool is provided by Atmel.
47.7 UTMI PLL Characteristics
The following characteristics are applicable to the operating temperature range: T
A
= -40°C to 85°C and worst case of
power supply, unless otherwise specified.
