INS6102B
Manufacturer: DAPU
The INS6102B is a clock buffer that distributes one reference clock to several destinations while adding only 0.35 ps of jitter. Added jitter is the number that matters in a clock distribution part: it is the noise the buffer itself contributes on top of the reference, and in a GNSS receiver or a high-speed serial link it translates directly into performance loss. Keeping it at 0.35 ps is what makes the part suitable for those roles.
Overview
The INS6102B is a 1:2 low-jitter clock buffer from DAPU designed to fan out a single master clock to multiple peripherals. It accepts a square or sine wave input at 10 – 80 MHz, with a minimum sine amplitude of 0.3 V peak to peak, and provides two LVCMOS outputs. Added phase jitter is 0.35 ps for an LVCMOS input at 26 MHz and 0.40 ps for a sine input, measured over a 10 Hz to 5 MHz bandwidth.
Two clock request inputs, CLK_REQ1 and CLK_REQ2, gate the corresponding output so unused blocks can be shut down. An integrated LDO accepts 2.3 – 5.5 V and produces a 1.8 V, 50 mA rail for peripherals, and the device also performs level translation between 1.8 V and 1.2 V domains. It comes in a WCSP package measuring 0.78 x 1.58 mm, rated -40 to +85 °C, aimed at portable terminals such as phones and GNSS receivers.
