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.
