Pin Descriptions QSOP Pin# Name Function 1STSET Loss of signal threshold setting input. Connect a 1% resistor between this pin and VCC3 (pin 2) to set loss of signal threshold. 2VCC3 Power supply input for 3.3V applications or the output of the internally regulated 3.3V voltage when VCC = 5V. Connect directly to supply for 3.3V applications (internal regulator not in use). Do not connect to power supply if VCC = 5V. 3 GND Ground. 4 DINP Non-inverting data input. Internally terminated with 50 Ω to VTT (see Figure 3-2). 5 DINN Inverting data input. Internally terminated with 50 Ω to VTT (see Figure 3-2). 6 NC No Connect. Leave Floating. 7VCC3 Power supply input for 3.3V applications or the output of the internally regulated 3.3V voltage when VCC = 5V. Connect directly to supply for 3.3V applications (internal regulator not in use). Do not connect to power supply if VCC = 5V. 8 JAM Output disable. When high, data outputs are disabled (with non-inverting output held high and inverting output held low). Connect to LOS output to disable outputs with loss of signal. Outputs are enabled when JAM is low or floating. Internal 150 k Ω resistor to ground. 9 LOS Loss of signal output. Goes high when input signal falls below threshold set by STSET. This output is an open collector TTL with internal 80 k Ω pull-up resistor to VCC. Leave floating if not used. 10 ST Signal detect output. Goes high when input signal amplitude is above threshold set by STSET. In M02046-15, this output is an open collector TTL with internal 80 k Ω pull-up resistor to VCC; In M02046-25, this output is PECL. Leave floating if not used. 11 GND Ground. 12 PECLN Inverting data output (PECL). 13 PECLP Non-inverting data output (PECL). 14 VCC Power supply. Connect to either +5V or +3.3V. 15 NC No Connect. Leave Floating. 16 IREF Internal reference current for the LOS threshold. Must be connected to ground through a 12.1 k Ω 1% resistor. |
