Description
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. 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
Overview
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. 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.
