Pin Description Pin BGA QFN Name I/O Description C2 1 VTCLK − Internal 50 W Termination Pin. See Table 4. C1 2 CLK ECL, CML, LVCMOS, LVDS, LVTTL Input Inverted Differential Input. B1 3 CLK ECL, CML, LVCMOS, LVDS, LVTTL Input Noninverted Differential Input. B2 4 VTCLK − Internal 50 W Termination Pin. See Table 4. A1 5 VTD − Internal 50 W termination pin. See Table 4. A2 6 D ECL, CML, LVCMOS, LVDS, LVTTL Input Inverted Differential Input. A3 7 D ECL, CML, LVCMOS, LVDS, LVTTL Input Noninverted Differential Input. A4 8 VTD − Internal 50 W Termination Pin. See Table 4. D1,B3 9,16 VCC − Positive Supply Voltage B4 10 Q RSECL Output Inverted Differential Output. Typically Terminated with 50 W Resistor to VTT = VCC − 2 V. C4 11 Q RSECL Output Noninverted Differential Output. Typically Terminated with 50 W Resistor to VTT = VCC − 2 V. C3 12 VEE − Negative Supply Voltage D4 13 OLS* Input Input Pin for the Output Level Select (OLS). See Table 2. D3 14 SEL LVECL, LVCMOS, LVTTL Input Select Logic Input. Internal 75 k W to VEE. D2 15 R LVECL, LVCMOS, LVTTL Input Reset D Flip−Flop. Internal 75 k W to VEE. N/A − EP Exposed Pad. (Note 1) 1. All VCC and VEE pins must be externally connected to Power Supply to guarantee proper operation. The thermally exposed pad (EP) on package bottom (see case drawing) must be attached to a heat−sinking conduit. 2. In the differential configuration when the input termination pins (VTD, VTD, VTCLK, VTCLK) are connected to a common termination volt- age, and if no signal is applied then the device will be susceptible to self−oscillation. 3. When an output level of 400 mV is desired and VCC − VEE > 3.0 V, 2KW resistor should be connected from OLS pin to VEE. |
