Precision Edge® PrecisionSY100EL29V Edge® 5V/3.3V DUAL DIFFERENTIAL DATA AND CLOCK D FLIP-FLOP w/SET AND RESET Micrel, Inc. SY100EL29V FEATURES ■ 3.3V and 5V power supply option ■ Differential D, CLK and Q ■ Extended VEE range of –3.0V to –5.5V Precision Edge® DESCRIPTION ■ ■ ■ ■ VBB output for single-ended use 1100MHz min. toggle frequency Asynchronous Reset and Set Fully compatible with Motorola MC100LVEL29 and MC100EL29 ■ Available in 20-pin SOIC package The SY100EL29V is a dual differential register with differential data (inputs and outputs) and clock. The registers are triggered by a positive transition of the positive clock (CLK) input. A HIGH on the Reset (Rx) asynchronously resets the appropriate register so that the Q outputs go LOW. A HIGH on the Set (S x ) asynchronously resets the appropriate register so that the Q outputs go HIGH. The Set and Reset inputs cannot both be HIGH simultaneously. The differential input structures are clamped so that the inputs of unused registers can be left open without upsetting the bias network of the devices. The clamping action will assert the /D and the /CLK sides of the inputs. The noninverting input will pull down to VEE and the inverting input will be biased around VCC/2. Because of the edge-triggered flip-flop nature of the devices, simultaneously opening both the clock and data inputs will result in an output which reaches an unidentified but valid state. The fully differential design of the devices makes them ideal for very high frequency applications where a registered data path is necessary.

VCMR is referenced to the most positive side of the differential input signal. Normal operation is obtained when the input signals are within the VCMR range and the input swing is greater than VPP(Min.) and <1V. The lower end of the VCMR range varies 1:1 with VEE. The numbers in the spec table assume a nominal VEE = –3.3V. Note for PECL operation, the VCMR(Min) will be fixed at 3.3V – |VCMR(Min)|. 2. Minimum input swing for which AC parameters are guaranteed.
