Overview

•
The S19256 is a fully integrated low power dual
CDR device suitable for short reach module
applications. It is used in 10GbE / 10GFC / OC192 SONET/SDH PMD modules, such as the XFP
MSA modules. Integrated in this device on the
receive optical side, an AGC amplifier with offset
cancellation circuitry, and CDR. On the transmit
electrical side the S19256 also has an
equalization circuit, and CDR that reshapes the
data after up to 24" of transmission over copper
on FR-4 PWB material, with low jitter generation
of 25 mUI. For SFP+ applications, this device
allows both CDR’s to be powered-down and
bypassed while using only the equalization
circuitry needed to mitigate Data Dependent
Jitter caused by the interconnect. The low-jitter
CML interface guarantees compliance with the
bit error rate requirements of the Telcordia and
ITU-T standards. The S19256 is packaged in a
6x6 mm2 PBGA, offering designers a small
package outline.
The S19256 can be used to implement the front
end of SONET/SDH/FEC/10GbE/FC/G.709
equipment which consists primarily of the serial
transmit interface and the serial receive
interface. The system timing circuitry consists of
a high-speed phase detector, clock and data
recovery unit and equalization circuitry. The
device utilizes on-chip clock recovery PLL
components that allow the use of a slower
external clock reference, 155.52 MHz (or
equivalent FEC/10GbE/10 Gbps FC rate), in
support of existing system clocking schemes.

XFP MSA Modules (2 km, 10 km, and 40 km)
Value Proposition - Design multiple XFP
modules ranging from 2 km to 120 km link with
one footprint. The S19256 (no EDC) is pin
compatible to the EDC based 10G Dual CDR
S19233.
S19256: 2 km-30 km;
S19233: 2 km-120 km
On the transmitter side, an equalizer is
integrated in the receive front end to reshape
the data after transmission over FR-4. This
enables low bit error rate and transmission over
longer trace length.
The low-jitter, 1-bit, CML interfaces guarantee
compliance with the bit-error rate requirements
of the Telcordia and ITU-T standards. The
10 Gbps serial electrical interface specifications
are compliant with the XFI as specified in the
XFP MSA module specification. The high speed
serial input and output can be connected to the
AMCC SerDes (S19235 or S19237) across 60 cm
(24”) of improved FR-4 material or across 40 cm
of standard FR-4 with one connector.
