HEF4040B
Datasheet
General description
The HEF4040B is a 12-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and twelve fully buffered outputs (O0 to O11 ). The counter advances on the HIGH to LOW transition of CP. A HIGH on MR clears all counter stages and forces all outputs LOW, independent of CP. Each counter stage is a static toggle flip-flop. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
Features
- Data and clock recovery up to 2.5 Gbits/s (STM1/OC3, STM4/OC12 and STM16/OC48)
- Differential data input with 2.5 mV peak-to-peak typical sensitivity
- Differential CML (Current-Mode Logic) data and clock outputs with 50 W driving capability
- Adjustable CML output level
- Loop mode for system testing
- BER related LOS detection
- Few external components needed
- LQFP48 plastic package
- Power dissipation typical 350 mW
- Single supply voltage.
