SY89230U
Overview
The SY89230U is a precision, low jitter 3.2 GHz ÷3, ÷5 clock divider with an LVPECL output. The differential input includes Micrel’s unique, 3-pin internal termination architecture that allows the input to interface to any differential signal (AC- or DCcoupled) as small as 100mV (200mVPP) without any level shifting or termination resistor networks in the signal path.
- Accepts a high-speed input and provides a precision ÷3 and ÷5 sub-rate, LVPECL output
- Guaranteed AC performance over temperature and supply voltage: - DC-to >3.2 GHz throughput - < 850ps Propagation Delay (In-to-Q) - < 200ps Rise/Fall times
- Ultra-low jitter design: - <1psRMS random jitter - <1psRMS cycle-to-cycle jitter - <10psPP total jitter (clock) - <0.7psRMS MUX crosstalk induced jitter
- Unique patented internal termination and VT pin accepts DC- and AC-coupled inputs (CML, PECL, LVDS)
- Wide input voltage range VCC to GND
- 800mV LVPECL output
- TBD% to TBD% Duty Cycle
- 2.5V ±5% or 3.3V ±10% supply voltage
- -40°C to +85°C industrial temperature range
- Available in 16-pin (3mm x 3mm) MLF® package
