X-axis data first. EYEOUT is synchronous with the rising edge of EYECLK. EYE-
OUT is valid only while the EYESTB is Low. Data is shifted out MSB first.
Data on eyeout is shifted out on each rising edge of the 1.536MHz EYECLK. EYE-
OUT data is valid on the following edge of the EYE PATTERN CLOCK, EYECLK.
The EYEOUT data is valid when the EYE PATTERN STROBE, EYESTB, is Low. EYE-
STB changes state on the rising edge of EYECLK.

modulation method.
The Z02201 provides comprehensive and flexible tone generation and detection,
including all tones required to establish a circuit connection and to setup and
control a communication session. The tone generation furnishes the DTMF tones
for PSTN auto dialing, and the supervisory tones for call establishment. The tone
detection provides support for call-progress monitoring. The detector can also be
user-programmed to recognize up to 16 tones.
The data encoding for the Z02201 meets both ITU–T recommendations and Bell
standards.
