The DS21600/DS21602/DS21604 are multiple-rate clock adapters that convert between E-Carrier and T-Carrier clocks rates. A T1 or E1 clock output, CLKOUT1, is available, along with a higher multiple rate clock output, CLKOUT2. CLKOUT1 and CLKOUT2 are frequency locked to the clock input CLKIN. The clock outputs, along with frame-sync output, can be phase-aligned to a frame-sync input. The devices are fully compatible with the LXP600A, LXP602, and LXP604, and operate from either a 5V or 3.3V supply. All operation modes include a standard 8kHz output. The DS21600/DS21602/DS21604 are available in 16-pin SO, and are rated for industrial temperatures. * Direct drop-in replacement for LXP600ASE, LXP602SE, and LXP604SE * Converts E-Carrier clock rates to T-Carrier clock rates * Converts T-Carrier clock rates to E-Carrier clock rates * 3.3V or 5V supply * Low jitter output * Multiple output clocks synchronized to input clock * 8kHz frequency-locked output for all operation modes * No external components required * 16-Pin SO and 8-Pin DIP * Industrial temperature range: -40°C to +85°C
