Electrical Characteristics

NOTE

CKIL is approximately 32 kHz. TCKIL is one period or approximately

μs.

4.6.3

Clock Amplifier Parameters (CKIH)

The input to clock amplifier (CAMP) is internally ac-coupled allowing direct interface to a square wave or

sinusoidal frequency source. No external series capacitors are required.

Table 37 shows the electrical parameters of CAMP.

4.6.4

DPLL Electrical Parameters

Table 38 shows the electrical parameters of digital phase-locked loop (DPLL).
