swings, which are referenced to +5.0 V. When SERIN–
is grounded, the Am7969 is put into Test Mode; SERIN+
becomes a single-ended ECL input, the PLL clock gen-
erator is bypassed, and X1
determines the bit rate
(rather than the byte rate). Both pins have internal pull
down resistors which cause unterminated inputs to
stay low.

VLTN
Violation (TTL Output)
The rising edge of this output indicates that a transmis-
sion error has been detected. It changes state at the
same time DOi or COi
change and will be followed by
either DSTRBor CSTRB This pin goes LOW when the
next valid byte is decoded.
X1, X2
Crystal Oscillator Inputs (Inputs)
These two crystal input pins connect to an internal paral-
lel/mode oscillator which oscillates at the fundamental
frequency external crystal. During normal operation, the
byte rate is set by the crystal frequency. Alternatively,
X1 can be driven by an external frequency source. In
multiple TAXI systems, this external source could be a
TAXI Transmitter’s CLKoutput or an external TTL fre-
quency source.
