Features
• ZL50212 has nine Echo Voice Processors in a
single BGA package. This single device provides
288 channels of 64 msec echo cancellation or 144
channels at 128 msec echo cancellation
• Each Echo Voice Processor has the capability of
cancelling echo over 32 channels
• Each Echo Voice Processor (EVP) shares the
address bus and data bus with each other
• Fully compliant to ITU-T G.165, G.168 (2000) and
(2002) specifications
• Passed all AT&T voice quality tests for carrier
grade echo canceller
• The ZL50212 provides more than 63% board
space savings when compared with the nine Echo
Voice Processors packaged devices
• Each EVP has a Patented Advanced Non-Linear
Processor with high quality subjective performance
• Each EVP has protection against narrow band
signal divergence and instability in high echo
environments
• Each EVP can be programmed independently in
any mode e.g. Back-to-Back or Extended Delay to
provide capability of cancelling different echo tails.
• Each EVP has 0 to -12 dB level adjusters at all
signal ports (Rin, Sin, Sout and Rout)
• Each EVP has the same JTAG identification code

Description
The ZL50212 Voice Echo Canceller implements a cost
effective solution for telephony voice-band echo
cancellation conforming to ITU-T G.168 requirements.
The ZL50212 architecture contains 144 groups of two
echo cancellers (ECA and ECB) which can be
configured to provide two channels of 64 milliseconds
or one channel of 128 milliseconds echo cancellation.
This provides 288 channels of 64 milliseconds to 144
channels of 128 milliseconds echo cancellation or any
combination of the two configurations. The ZL50212
supports ITU-T G.165 and G.164 tone disable
requirements.

K2 Test Mode Select (3.3V Input). JTAG signal that
controls the state transitions of the TAP controller. This
pin is pulled high by an internal pull-up when not
driven. This signal is connected to all processors.
D6 Test Clock (3.3V Input). Provides the clock to the
JTAG test logic.This signal is connected to all
processors.
D7 Test Reset (3.3V Input). Asynchronously initializes
the JTAG TAP controller by putting it in the
Test-Logic-Reset state. This pin should be pulsed low
on power-up or held low, to ensure that all the EVP’s
are in the normal functional mode. This pin is pulled by
an internal pull-down when not driven. This signal is
connected to all EVP’s.
