The new DS3102 from Maxim is said to be the industry's first timing-card IC to provide full carrier-class, Stratum 3 clock synchronisation for G.8262-compliant synchronous Ethernet (Sync-E) equipment.
The device features two independent DPLLs (digital phase-locked loops), one for creating the main system clock and one for generating derived DS1/E1 clocks to send to an external BITS/SSU through DS1/E1 transceivers. The device provides impressive frequency agility, while supporting all common system clock rates for SONET/SDH, PDH, synchronous Ethernet, and wireless base stations. It is suitable for use in timing cards in a wide variety of wireline and wireless systems, including ADMs, digital cross-connects, carrier-class switches and routers, wireless base stations, DSLAMs, and multiservice access nodes.
The DS3102 continually monitors up to eight input clocks, each of which can be assigned to either of the two internal DPLLs. Inputs are continuously monitored for activity and frequency and can be automatically qualified and disqualified by the device according to configurable criteria. The eight clock inputs accept all common telecom clock rates, as well as all multiples of 2 kHz up to 131,072 MHz, and all multiples of 8 kHz up through 155,52 MHz (differential) or 125 MHz (single-ended).
The chip can simultaneously produce a total of seven output-clock frequencies plus 2 kHz and 8 kHz frame pulses. Each output clock can be frequency-locked to either of the two DPLLs. The output clocks have the same frequency options as the input clocks, plus differential-signal rates as high as 312,5 MHz. In addition, programmable synthesis engines can produce any multiple of 2 kHz up to 77,76 MHz, any multiple of 8 kHz up to 311,04 MHz, any multiple of 10 kHz up to 388,79 MHz, and many other frequencies as needed.
The DS3102 has an SPI-compatible serial interface and is packaged in an 81-lead, 10 x 10 mm BGA. It is fully specified over the -40°C to +85°C temperature range, and an RoHS-compliant package option is available.
