2. FUNCTIONAL DESCRIPTION
2.1 - Clock Signal
The STA014 input clock is derivated from an ex-
ternal source or from a industry standard crystal
oscillator, generating input frequencies of 10,
14.31818 or 14.7456 MHz.
CMOS compatibility
The XTI pad low and high levels are CMOS compatible; XTI pad noise margin is better than typical
CMOS pads.
TTL compatibility
The XTI pad low level is compatible with TTL while the high level is not compatible (for example if V
3V TTL min high level = 2.0V while XTI min high level = 2.2V)
