Gull Wing Delay Lines US Patent 5,365,203 GL1L / GL2L 16 Pin Series 1.0 Description These delay lines offer the same excellent frequency performance as the SIP delay lines, but come in a gull winged surface mount package. The differential SMT is useful for PECL applications, and contains two identical transmission lines matched for time delay. Featuring a stripline shielded construction, these parts offer very low EMI/RFI, and are ideal for high frequency/tight tolerance timing and deskew applications. 2.0 Mechanical - Please refer to page 43 for land pattern dimension mm 13.55 max 2 10 GL1L - Single 1 3 4 MS250S E 9 11 16 6.05 max 8.35 max 16 15 14 13 12 11 10 9 1.15 0.25 1.88 0.25 GL2L - Coupled Differential 1.27 0.13 0.28 H 0.05 0.41 max 0.56 max 0.10 1 2 3 4 5 6 7 8 Time delay Height (H) Code 0.1 - 1.0 ns 2.37 max L 1.1 - 5.0 ns 4.85 max M 3.0 Electrical TYPE Time Delay GL1L (Single) 0.1~5.0 ns (0.1 ns step) Time delay tolerance 0.05 ns Rise/fall time Impedance Temp coefficient of Td Rated current Rated voltage DC resistance Isolation resistance Operating temperature Storage temperature GL2L (Differential) 0.1~3.0 ns (0.1 ns step) 3.5~4.5 ns (0.5 ns step) 50 from 0.1 to 2.9 ns -50/+100 ps for 3.0 ns 100 ps for 3.5 to 4.5 ns 200 ps/ns 50 ohm 5 ohm 0 to +150 ppm/C 100 mA 100 Vdc (1 min) 1.0 ohm/ns max >100 Mohm @ 50Vdc -40C to +85C -55C to +125C 4.0 Part Number GL Product designator Circuit/element qualifier (1 = 1 element), (2 = 2 elements) 1L Impedance (5 = 50 ohm) 5 Height code M Lead frame S Time delay (250 = 2.50 ns) *** Serial code (S = Single ended), (D = Differential) S Packaging (T = tape), (1 = 100) R I S TERE EG I S TERE D EG D R T1 ISO9001 ISO14001 A4 A8 303 561 Manufacturer(s) of the products described on this page are indicated by their respective logos. 4
