MC1EP446, MC1EP446 3.3 V/5 V 8 Bit CMOS/ECL/TTL ata Input Parallel/Serial Converter escription The MC1/1EP446 is an integrated 8 bit parallel to serial data converter. The device is designed with unique circuit topology to operate for NRZ data rates up to 3.2 Gb/s. The conversion sequence from parallel data into a serial data stream is from bit to 7. The parallel input pins 7 are configurable to be threshold controlled by CMOS, ECL, or TTL level signals. The serial data rate output can be selected at internal clock data rate or twice the internal clock data rate using the CKSEL pin. Control pins are provided to reset () and disable internal clock circuitry (CKEN). In either CKSEL modes, the internal flip flops are triggered on the rising edge for and the multiplexers are switched on the falling edge of, therefore, all associated specification limits are referenced to the negative edge of the clock input. Additionally, V BB pin is provided for single ended input condition. The 1 Series devices contain temperature compensation network.

MC1EP446, MC1EP446 APPLICATION INFORMATION The MC1/1EP446 is an integrated 8:1 parallel to serial converter. An attribute for EP446 is that the parallel inputs 7 (Pins 17 24) can be configured to accept either CMOS, ECL, or TTL level signals by a combination of interconnects between V EF (Pin 27) and V CF (Pin 26) pins. For CMOS input levels, leave V EF and V CF open. For ECL operation, short V CF and V EF (Pins 26 and 27). For TTL operation, connect a 1.5 V supply reference to V CF and leave the V EF pin open. The 1.5 V reference voltage to V CF pin can be accomplished by placing a 1.5 k or 5 between V CF and V EE for 3.3 V or 5. V power supplies, respectively. Note: all pins requiring ECL voltage inputs must have a 5 terminating resistor to V TT (V TT = 2. V). The CKSEL input (Pin 2) is provided to enable the user to select the serial data rate output between internal clock data rate or twice the internal clock data rate. For CKSEL LOW operation, the time from when the parallel data is latched to when the data is seen on the S OUT is on the falling edge of the 7 th clock cycle plus internal propagation delay (Figure 7).

MC1EP446, MC1EP446 Similarly, for CKSEL HIGH operation, the time from when the parallel data is latched to when the data is seen on the S OUT is on the rising edge of the 14 th clock cycle plus internal propagation delay (Figure 8).

MC1EP446, MC1EP446 The device also features a differential input (Pins 29 and 3), which asynchronously reset all internal flip flops and clock circuitry on the rising edge of. The release of is a synchronous process, which ensures that no runt serial data bits are generated. The falling edge of the followed by a falling edge of initiates the start of the conversion process on the next rising edge of (Figures 9 and 1).

MC1EP446, MC1EP446 The differential synchronous CKEN inputs (Pins 6 and 7), disable the internal clock circuitry. The synchronous CKEN will suspend all of the device activities and prevent runt pulses from being generated. The rising edge of CKEN followed by the falling edge of will suspend all activities.

Timing iagram with CKEN with CKSEL HIGH The differential P output (Pins 14 and 15) is a word framer and can help the user synchronize the serial data output, S OUT (Pins 11 and 12), in their applications. Furthermore, P can be used as a trigger for input parallel data (Figure 14). An internally generated voltage supply, the V BB pin, is available to this device only. For single ended input conditions, the unused differential input is connected to V BB as a switching reference voltage. V BB may also rebias AC coupled inputs. When used, decouple V BB and via a.1 F capacitor and limit current sourcing or sinking to.5 ma. When not used, V BB should be left open. Also, both outputs of the differential pair must be terminated (5 to V TT ) even if only one output is used.
