SY89231U
Overview
The SY89231U is a precision, low jitter 3.2GHz ÷3, ÷5 clock divider with a LVDS 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, LVDS output
- Guaranteed AC performance over temperature and supply voltage: - DC-to >3.2GHz throughput - <810ps 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
- 325mV LVDS output
- 45% to 55% Duty Cycle (÷ 3)
- 47% to 53% Duty Cycle (÷ 5)
- 2.5V ±5% supply voltage
- -40°C to +85°C industrial temperature range
