Description

The TLK10232 is a dual-channel multi-rate transceiver intended for use in high-speed bi-directional point-

to-point data transmission systems. This device supports three primary modes. It can be used as a XAUI

to 10GBASE-KR transceiver, as a general-purpose 8b/10b multi-rate 4:1, 2:1, or 1:1 serializer/deserializer,

or can be used in 1G-KX mode.

While operating in the 10GBASE-KR mode, the TLK10232 performs serialization of the 8B/10B encoded

XAUI data stream presented on its low speed (LS) side data inputs. The serialized 8B/10B encoded data

is presented on the high speed (HS) side outputs in 64B/66B encoding format. Likewise, the TLK10232

performs deserialization of 64B/66B encoded data streams presented on its high speed side data inputs.

The deserialized 64B/66B data is presented in XAUI 8B/10B format on the low speed side outputs. Link

Training is supported in this mode as well as Forward Error Correction (FEC) for extended length

applications.

While operating in the General Purpose SERDES mode, the TLK10232 performs 2:1 and 4:1 serialization

of the 8B/10B encoded data streams presented on its low speed (LS) side data inputs. The serialized

8B/10B encoded data is presented on the high speed (HS) side outputs. Likewise, the TLK10232 performs

1:2 and 1:4 deserialization of 8B/10B encoded data streams presented on its high speed side data inputs.

The deserialized 8B/10B encoded data is presented on the low speed side outputs. Depending on the

serialization/deserialization ratio, the low speed side data rate can range from 0.5 Gbps to 5 Gbps and the

high speed side data rate can range from 1 Gbps to 10 Gbps. 1:1 retime mode is also supported but

limited to 1 Gbps to 5 Gbps rates.

The TLK10232 also supports 1G-KX (1.25 Gbps) mode with PCS (CTC) capabilities. This mode can be

enabled via software provisioning or via auto negotiation. If software provisioning is used, data rates up to

3.125 Gbps are supported.

The TLK10232 features a built-in crosspoint switch, allowing for redundant outputs and easy re-routing of

data. Each output port (either high speed or low speed) can be configured to output data coming from any

of the device’s input ports. The switching can be initiated through either a hardware pin or through

software control, and can be configured to occur either immediately or after the end of the current packet.

This allows for switching between data sources without packet corruption.

Both low speed and high speed side data inputs and outputs are of differential current mode logic (CML)

type with integrated termination resistors.

The TLK10232 provides flexible clocking schemes to support various operations. They include the support

for clocking with an externally-jitter-cleaned clock recovered from the high speed side. The device is also

capable of performing clock tolerance compensation (CTC) in 10GBASE-KR and 1GBASE-KX modes,

allowing for asynchronous clocking.

The TLK10232 provides low speed side and high speed side loopback modes for self-test and system

diagnostic purposes.

The TLK10232 has built-in pattern generators and verifiers to help in system tests. The device supports

generation and verification of various PRBS, High-/Low-/Mixed-Frequency, CRPAT long/short, CJPAT,

and KR pseudo-random test patterns and square wave generation. The types of patterns supported on the

low speed and high speed side are dependent on the operational mode chosen.

The TLK10232 has an integrated loss of signal (LOS) detection function on both high speed and low

speed sides. LOS is asserted in conditions where the input differential voltage swing is less than the LOS

assert threshold.

Both TLK10232 channels are fully independent. They can be operated with different reference clocks, at

different data rates, and with different serialization/deserialization ratios.
