The TLK1101E is a versatile and flexible high-speed equalizer for applications in digital high-speed links with data rates up to 11.3Gbps.
●The TLK1101E can be configured in many ways to optimize its performance. It provides output de-emphasis adjustable from 0dB to 7dB using pins DE0 and DE1.
●The output differential voltage swing can be set to 300mVp-p, 600mVp-p, or 900mVp-p using the SWG pin. A controlling voltage on pin VTH can be used to adjust the input threshold voltage.
●Pins LN0 and LN1 can be used to optimize the device performance for various interconnect lengths, e.g. from 0 to 20 meters of 24-AWG twinaxial cable.
●The LOS (loss of signal) assert level can be set to a desired level through a controlling voltage connected to pin LOSL. The LOS assert levels can be chosen from two LOS assert level ranges selectable with the LOSR pin.
●The output can be disabled using the DIS pin. The DIS and the LOS pin can be connected together to implement a squelch function.
●The de-emphasis, the output voltage swing, the input threshold voltage, the output disable, and the LOS assert levels and ranges can alternatively be set using the two-wire serial interface through the SCL and SDA pins. The external pin configuration is the default device setup method. The active device control method is selected through register address 0 bit 0 (see Table 4 and Table 20). The two-wire serial interface also allows for the control of the input bandwidth to optimize the device performance for various data rates.
●The high input signal dynamic range ensures low jitter output signals even when overdriven with input signal swings as high as 1600mVp-p differential.
●The low-frequency cut-off is low enough to support low-frequency control signals such as SAS and SATA out-of-band (OOB) signals.
