| SY88063AL 3.3V, 12.5Gbps Limiting Post Amplifier with Automatic Digital Offset Correction The SY88063AL is a multi-rate limiting post amplifier designed for fiber-optic transceivers applications up to 12.5Gbps. It features an automatic digital offset correction function. The offset correction feature will automatically counteract any inherent offset present in the input signal and amplifier. The highly sensitive SY88063AL can amplify input signals as low as 20mVpp at 12.5Gbps or 10mVpp at 10.3Gbps to differential CML output levels. The SY88063AL generates a loss-of-signal LOS opencollector TTL output. A programmable loss-of-signal level set pin LOSLVL sets the sensitivity of the input amplitude detection. LOS asserts high if the input amplitude falls below the threshold set by LOSLVL and de-asserts low otherwise. The enable input /EN de-asserts the true output signal without removing the input signal. The LOS output can be fed back to the /EN input to implement the squelch function that maintains output stability under a loss-of-signal condition. The SY88063AL operates from a single +3.3V power supply, over to +85oC, and is available in 3mm x 3mm 16-pin QFN package.

Ordering Information Part Number SY88063ALMG TR 1 Note Tape and Reel. Package Type Lead-Free QFN-16 Lead-Free QFN-16 Pin Configuration Operating Range Industrial SY88063AL Package Marking 063A with Pb-Free Bar Line Indicator 063A with Pb-Free Bar Line Indicator 3mm x 3mm QFN-16 Pin Description Pin Number Pin Name DIN, /DIN 5, 6, 14, 16 LOSLVL 10, 11 /DOUT, DOUT Type Data Input No Connection Open-Collector TTL Output DC Input CML Output Pin Function Differential data inputs. Each input is internally terminated to approximately VCC 1.3V by a resistor. AC-Couple input signals. Unused Pins. Leave open. Loss-of-Signal Asserts HIGH when the data input amplitude falls below the threshold set by LOSLVL. Loss-of-Signal Level Set. A resistor from this pin to VCC sets the threshold for the data input amplitude at which LOS will be asserted. Differential Data Outputs. Unused output should be terminated September 2011 M9999-090911-B or 408 955-1690 Micrel, Inc. SY88063AL Pin Description Continued Pin Number 13 15 1, 4 9, 12 Pin Name LOCKED /EN GND VCC Type LVTTL Output LVTTL Input Ground Power Supply Pin Function Once digital offset correction is locked based input signal, this pin will output a LVTTL HIGH. /Enable This input enables the outputs when it is LOW. Note that this input is internally connected to a pull-up resistor and will default to a logic HIGH state if left open. Device Ground. Exposed pad must be soldered or equivalent to the same potential as the ground pins. Positive Power Supply. Bypass with 0.1uF | | 0.01uF low ESR capacitors. 0.01uF capacitors should be as close as possible to VCC pins. |
